An ostomy coupling has a first coupling member and a second coupling member. These are mutually interengageable and surround a region which includes a stomal orifice. A springy resilient ring encircles the two coupling members and has a handle member which can be manipulated to cause the ring to be deformed such that radially-inwardly extending tabs on the ring are shifted between respective first positions in which the ring is undeformed and the tabs lock the two coupling members together and respective second positions in which the ring is deformed in such a way as to shift the tabs radially outwardly to positions where they permit separation of the two coupling parts. The ring has a portion which joins the ends of two limbs of the ring, said portion being readily deformable and optionally sufficiently elastic such that the limb ends are pulled towards each other by the elasticity of said portion. |
