How do interchangeable O-rings work on a strap-on harness? The O-ring is the ring at the front of the harness that the dildo passes through. The dildo's flared base sits behind the ring and holds it in place. A ring that is too big lets the dildo wobble or slip out, and one that is too small will not go over the shaft. This harness comes with three rings, at 1.25, 1.5 and 2 inches in diameter, so you can match the ring to the dildo you plan to wear.
Horny Devil strap-on harness with creature eye and horns
The Horny Devil is a strap-on harness from the Creature Cocks range, made to go with fantasy dildos. A creature eye sits on the front and two vegan-leather horns rise above the O-ring. The harness is PU leather with nickel-free buckles and D-rings. The waist adjusts from 31 to 45 inches and the thigh straps extend up to 23 inches.
The back is open, which leaves the wearer free to move and accessible from behind. A wide back strap helps carry the weight of heavy dildos. Three O-rings are supplied, in 1.25, 1.5 and 2 inch diameters. The harness is offered in red or green.
Best for: For anyone who wants to wear a fantasy or creature dildo, especially a heavy one that needs solid support. The adjustable straps fit waists from 31 to 45 inches. A dildo is not included, so pair it with one that has a flared base.

How to use
Choose the O-ring that fits snugly around the shaft of your dildo and fit it to the front of the harness. Push the dildo through from behind so its flared base rests against the inside of the ring. Step into the thigh straps, pull the harness up and fasten the waist. Tighten the waist first, then the thighs, until the base sits firmly against your body and does not sag. Check that the back strap is flat. Give the dildo a tug to confirm it is secure before you start.
Care
- Take the dildo and O-ring out before cleaning.
- Wipe the PU leather with a damp cloth and a little mild soap, then dry it with a towel.
- Do not soak the harness or put it in a washing machine. Dry the metal buckles so they do not rust.
- Let it air dry flat, away from heat and direct sunlight.
- Store it unbuckled so the straps and horns keep their shape.

Frequently asked questions
What sizes does the harness fit?
The waist adjusts from 31 to 45 inches in circumference, and the thigh straps adjust up to 23 inches. Measure around your hips where the harness will sit, not your natural waist, and compare with those figures.
Does it come with a dildo?
No. The harness comes with three O-rings but no dildo. Use any dildo with a flared base that is wider than the O-ring you pick, so the ring can hold it securely.
Which O-ring should I use?
Pick the smallest ring the shaft will pass through. The three rings measure 1.25, 1.5 and 2 inches across. Slim dildos need the 1.25 inch ring, and thick fantasy dildos usually need the 2 inch one.
Can it hold a heavy fantasy dildo?
It is designed for that. The wide back strap is there to support the weight of heavy dildos, and the buckles and D-rings let you pull the fit tight so the dildo does not droop.
What is the difference between the red and green versions?
They are the same harness in two colors. Both have the creature eye, the two horns, the same open back, the same strap sizes and the same three O-rings in the box.
