QUICK-CONNECT COUPLING

摘要

The invention concerns a quick-connect coupling comprising a locking ring (20) arranged in a coupling body (10) to co-operate with a catching surface of a tube fitted into the coupling. Said ring is elastically deformable between an unlocking configuration and a locking configuration wherein at least a locking zone co-operates with the catching surface. For this, the ring comprises at least an unlocking hasp (22, 24) which projects through a slot of the coupling body. The locking zone comprises at least a tab (30A, 30B, 32A, 32B) formed by a protuberance, oriented inwards of the locking ring and having a free end.
