Abstract
A quick-connect coupling which includes a locking ring (20) disposed in an coupling body to co-operate with a catch surface on a tube fitted into the coupling. The ring is elastically deformable to go between an unlocking configuration and a locking configuration, in which at least one locking zone (30, 32) co-operates with the catch surface. To this end, the ring is provided with at least one unlocking bridge (22, 24) that protrudes through a slot in the body of the coupling. The ring is constituted by a strip that is plastically deformed to have at least the locking zone and the bridge. The ring forms a closed loop and has two ends (20A, 20B) which overlap, and which are suitable for sliding one over the other while the ring is being elastically deformed.
