Beaded collar:
"The red savages do not use steel collars. They use high, beaded collars, tied together in the front by a rawhide string. Subtle differences in the styles of collars, and in the knots with which they are fastened on the girls' necks, differentiate the tribes. Within a given tribe the beading, in its arrangements and colors, identifies the particular master. This is a common way, incidentally, for warriors to identify various articles which they own."
Savages of Gor, pg. 102, by John Norman.

Capture Collar:
" . . . I looked in the rear-view mirror, terrified. About my throat, closely looped, was a narrow golden chain. It was controlled by two narrow wooden handles, in his hands "It was a girl-capture chain," I said "It is to be distinqued from the standard garrote, which is armed with wire and can cut a throat easily. The standard garrote, of course, is impractical for captures, for the victim, in even a reflexive movement, might cut her own throat."
Savages of Gor, pg. 180, by John Norman.

Coffle collar
"The collars had front and back rings, were hinged on the right and locked on the left. This is a familiar form of coffle collar. The lengths of chain between the collars were about three to four feet long. Some were attached to the collar rings by the links themselves, opened and then reclosed about the rings, and some of them were fastened to the collar rings by snap rings."
Savages of Gor, pg. 135, by John Norman.

"Another common form of coffle collar has its hinge in the front and closes behind the back of the neck, like the common slave collar. It has a single collar ring, usually on the right, through which, usually, a single chain is strung. Girls are spaced on such a chain, usually, by snap rings."
Savages of Gor, pg. 135, by John Norman.

Cord collar:
" On some rence islands I have heard, incidentally, that the men have revolted, and enslaved their women. These are usually kept in cord collars, with small disks attached to them, indicating the names of their masters."
Vagabonds of Gor, pg. 341, by John Norman.

Dance Collar:
"A wrist ring was fastened on her right wrist. The long, slender, gleaming chain was fastened to this and, looping down and up, ascended gracefully to a wide chain ring on her collar, through which it freely passed, thence descending, looping down, and ascending, looping up, gracefully, to the left wrist ring. If she were to stand quietly, the palms of her hands on her thighs, the lower portions of the chain, those two dangling loops, would have been about at the level of her kneels, just a little higher. The higher portion of the chain, of course, would be at the collar loop."
Kajira of Gor, pg. 143, by John Norman.

Kur Collar:
"She approached me. From my pouch I drew forth a leather Kur collar, with its lock, and sewn in leather, its large, rounded ring. "What is it?" she asked apprehensively, I took it behind her neck, and then, closing it about her throat, thrust the large, flattish bolt, snapping it, into the locking breech. The two edges of metal, bordered by the leather, fitted closely together. The collar is some three inches in height. The girl must keep her chin up. "It is the collar of a Kur cow," I told her." Message Collar:
"Did you note the collar she wore?" He had not seemed to show much interest in the high thick leather collar that the girl had had sewn about her neck. "Of course" he said. "I myself," I said," have never seen such a collar." "It is a message collar," said Kamback. "Inside the leather sewn within, will be a message."
Nomads of Gor, pg. 40, by John Norman.

Northern Collar:
"Look up at me," said the smith. The slender, blond girl, tears in her eyes, looked up at him. He opened the hinged collar of black iron, about a half inch in height. He put it about her throat. It also contained a welded ring, suitable for the attachment of a chain. "Put your head beside the anvil," he said. He took her hair, and threw it forward, and thrust her neck against the left side of the anvil. Over the anvil lay the joining ends of the two pieces of the collar. The inside of the collar was separated by a quarter of an inch from her neck. I saw the fine hairs on the back of her neck. On one part of the collar are two, small, flat, thick rings. On the other is a single such ring. These rings, when the wings of the collar are joined, are aligned, those on one wing on top and bottom, that on the other in the center. They fit closely together, one on top of the other. The holes in each, about three-eighths of an inch in diameter, too, of course, are perfectly aligned. The smith, with his thumbs, forcibly, pushed a metal rivet through the three holes. The rivet fits snugly. "Do not move your head, Bond-maid," said the smith. Then, with great blows of the iron hammer, he riveted the iron collar about her throat.A man then pulled her by the hair from the anvil and threw her to one side. She lay there weeping, a naked bond-maid, marked and collared."
Marauders of Gor, pg. 105, by John Norman.

Plank Collar:
"The primary holding arrangement for women on the benches, however, are not chains. Each place on the bench is fitted with ankle and wrist stocks, and for each bench there is a plank collar, a plank which opens horizontally, each half of which contains five matching, semicircular openings, which, when it is set on pinions, closed, and chained in place, provides thusly five sturdy, wooden enclosures for the small, lovely throats of women. The plank is thick and thus the girl's chins are held high. The plank is further reinforced between each girl with a narrowly curved iron band, the open ends of which are pierced; this is slid tight in its slots, in its metal retainers, about the boards, and secured in place with a four-inch metal pin, which may or may not be locked in place."
Savages of Gor, pg. 60, by John Norman.

"Nearby there were four girls in a plank collar. This is formed from two boards into which matching semicircles have been cut. The two boards are connected and supported by five flat, slidining U-irons; when the U-irons are slid back, the collar is opened. When they are slid into palce, and the two leaves are bolted together, the collar is closed. Two hasps with staplesa, secured with padlocks, occur, too, at oppostive ends of the planks. These lock the collar. The four girls in the plan collar were kneeling, waiting for their master to conduct some business. he was of the peasants. They were nude. their hands were tied behind their backs."
Rogue of Gor, pg. 69, by John Norman.

Plate Collar:
"I could see the heavy metal collar hammered about the man's neck, not uncommon in a male slave. His head would have been placed across the anvil, and the metal curved about his neck with great blows."
Hunters of Gor, pg. 13, by John Norman.

Steel Band collar:
"The girls were then motioned to the anvil. First Virginia and then Phyllis laid their heads and throats on the anvil, head turned to the side, their hands holding the anvil, and the smith, expertly, with his heavy hammer and a ringing of iron, curved the collar about their throats; a space of a quarter of an inch was left between the two ends of the collar; the ends matched perfectly; both Virginia and Phyllis stepped away from the anvil feeling the metal on their throats."
Assassin of Gor, pg. 153, by John Norman.

Turian Collar:
The Turian collar lies loosely on the girl, a round ring; it fits so loosely that, when grasped in a man's fist, the girl can turn within it.
Nomads of Gor, pg. 29, by John Norman. 'The Turian collar lies loosely on the girl, a round ring; it fits so loosely that, when grasped in a mans fist, the girl can turn within it; the common Gorean collar, on the other hand, is flat, snugly fitting steel band. Both collars lock in the back, behind the girl's neck. The Turian collar is more difficult to engrave, but it, like the flat collar, will bear some legend assuring that the girl, if found, will be promptly returned to her Master.'
Nomads of Gor, pg. 19, by John Norman. Shipping Collar:
"What sort of collar do you wear?" "A shipping collar, Master. It shows that I am a portion of the cargo of the Palms of Schendi."
Explorers of Gor, pg. 79, by John Norman.

Collar Sleeve:
"I reached out, timidly, towards her throat. I touched the object there. "What is this?" I asked. "The silk?" she asked. "That is a collar stocking, or a collar sleeve. They may be made of many different materials. In a cooler climate they are sometimes of velvet. In most cities they are not used."
Kajira of Gor, pg. 46, by John Norman.

State collar:
"The female state slave of Ar wears a brief, gray slave livery, with matching gray collar. Save for the color it is identical with most common slave livery. About her left ankle is normally locked a gray steel band, to which five simple bells of gray metal, are attached."
Assassins of Gor, pg. 393, by John Norman.

String collar:
"Under the tether on the throat of each there was tied an intricately knotted set of four leather strings. In such a way the red hunters identify their animals. The owner of the beast may be determined from the knotting of the strings."
Beasts of Gor, pg. 153, by John Norman.

Vine collars:
"In the cities," she asked, "they have slave collars, do they not?"
"Yes," I said.
Then she had taken a length of marsh vine from a packet on her rence craft.
The, looking up into my eyes, smiling, close to me, her arms about my neck, she insolently wound the vine five times about my neck, and knotted it in front.
"Now," she said, "you have a collar."
"Yes," I said, "I have a collar."
"Say," said she, her arms still about my neck, "I am your collared slave."
My fists clenched. She stood within my grasp, her arms on my neck, taunting me with her eyes.
"I am your collared slave," I said.
Raiders of Gor, pg. 29, by John Norman.

Work collars:
"The two girls, on their hands and knees on the deck, linked together by a gleaming neck chain, some five feet in length, attached to two steel work collars, these fitted over their regular collars, looked up
Explorers of Gor, pg. 98, by John Norman.

Anklet:
"My ankles were crossed and tied together with a short piece of rope. A metal anklet of some sort was fastened on my left ankle." "A girls identificatory ankle," I said, "It is removed after her delivery to Gor."
