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.
An ostomy coupling, comprising:
An ostomy coupling comprising first and second coupling parts and an endless rotable locking ring for locking said first and second coupling parts, said ring having two limbs which together extend substantially around said ring and a joining portion of a stretchable elastic thermoplastics material joining the ends of said two limbs, said locking ring being expandable at said joining portion to an expanded position upon rotation of said ring to permit coupling and uncoupling of said first and second coupling parts and contractable at said joining portion from said expandable position to a resting position for locking said first and second coupling parts together.
