D-ring

The smallest part of your gear, and the only one that all the force runs through.

What is a D-ring?

D-ring (the same word in Dutch) is a metal ring shaped like a capital D that serves as an attachment point. The straight side is fixed to a strap of leather or fabric; on the rounded side you clip or tie something. On restraints, collars and harnesses the D-ring is the spot where rope, carabiner or chain takes hold.

What a D-ring is for

Coupling. The encyclopedia describes the D-ring as a piece of hardware, usually a metal ring shaped like a capital D, used mainly as a lashing or attachment point. It sits at the end of a leather or fabric strap, or is fixed to a surface with a strap or bracket; there are also versions with a center bar to weld to steel. A well-fixed D-ring swings freely.

That last part is exactly why it sits on restraints. A ring that can turn follows the direction of the pull, instead of tugging the strap sideways.

Why you come across it everywhere

Because the same piece of hardware turns out to be useful in almost every field. The same encyclopedia lists D-rings in climbing and caving, on saddles and bits, on dive vests, in truck beds, on dog collars, in ring binders, on transport belts for prisoners, and on BDSM restraints. One shape, dozens of worlds.

For bondage that mainly means: where the ring sits decides what is possible. A wrist cuff with a single D-ring on the outside you couple to a chain or to a fixed point in the dungeon; two cuffs with the rings against each other you clip to one another. What a ring can take varies from ring to ring: the encyclopedia names composition, shape, weight, finish and load rating as properties that vary per version. On a BDSM date with me, the D-ring is the point where the rope or the carabiner takes hold on the cuff.

Frequently asked questions

What people still ask about the D-ring.

  1. What is a D-ring?

    A D-ring is a metal ring shaped like a capital D that serves as an attachment point. The straight side is fixed to a strap; on the rounded side you couple rope, a carabiner or a chain.

  2. Where does a D-ring sit?

    On wrist cuffs, ankle cuffs, collars, harnesses and bodybags. Outside BDSM you come across the D-ring just as much on saddles, dive vests, dog collars and in truck beds: it is simply hardware.

  3. Are all D-rings the same?

    No. D-rings differ in composition, shape, weight, finish and load rating. So the shape tells you nothing about what a ring can take, and that is the one thing you cannot see from the outside.

  4. Who can you turn to with questions about gear like the D-ring?
