ABSTRACT:
An orifice coupling, e.g. an ostomy coupling, includes a first coupling part (10) securable to a second coupling part (20) by a springy split locking ring (30). The locking ring (30) is held captive on the first coupling member (10) by lugs (13) extending radially from outside the locking ring and which enable the locking ring (30) to engage the second coupling member (20) substantially continuously around the periphery of the second coupling member. The coupling can be released when the ends (26,27) of the locking ring (30) are manipulated to expand the ring. The locking ring (30) may be integrally moulded with the first coupling member, and folded into an operative position on the first coupling member.
