Fastener for key holder or pendant - has open loop whose flexible branches engage in locking ring

摘要

The fastener is for key holders, pendants or similar items and has two parts. One is an open loop (1) whose free extremities engage in the other part, which is a locking ring (2), to close the loop. The free extremities of the loop are flexible branches which each have a spur (4) on their extremities. These project from the locking ring when the fastener is closed and engage with the edge (9) of the ring to keep it closed.
