Coupling for ostomy appliance, and ostomy appliance comprising such a coupling
First Claim
1. A coupling for an ostomy appliance, comprising:
- first and second coupling members, each including a base defining a plane and equipped with a central opening, and a tubular joining piece surrounding said opening, the joining piece of the first member comprising, on an internal face, an elastically deformable annular lip whose free end is directed towards the plane of the base of said first member, and the joining piece of the second member including, on an external face, means for retaining axially the free end of said elastically deformable annular lip, and wherein said means occupies a part of the circumference of the tubular joining piece of the second coupling member, and guarantees, on that part of circumference, an axial retention of the free end of the annular lip of the first coupling member; and
wherein said coupling further includes a locking member which is either in one piece with the first coupling member or in one piece with the second coupling member, but which in either case is located diametrically opposite the midpoint of the means for axial retention of the free end of the annular lip.

Abstract
A coupling for an ostomy appliance, comprises two elements (10, 20), each including a base (11, 21), equipped with a central opening, and a tubular joining piece (12, 22) surrounding the opening. The joining piece (12) of the first element (10) comprises, on its internal face, an elastically deformable annular lip (18) whose free end (19) is directed towards the plane of the base (11) of the element. The joining piece (22) of the second element (20) includes, on its external face, means for axial retention (44) of the free end of this lip. This coupling includes a locking member (43), and the means for axial retention of the free end of the annular lip occupy a sector of the circumference of the joining piece of the second element, of which the midpoint is situated diametrically opposite the locking member under conditions of assembly and disassembly of the two elements of this coupling.
