D-ring
Strap attachment point
A D-ring is a metal or plastic ring shaped like the letter D, with one flat edge and one curved.
D-rings appear on bags, belts, harnesses, and straps as attachment points: Clip the leash to the D-ring on the collar.
They're common in outdoor gear, BDSM restraints, and military equipment where secure fastening matters.
