Abstract:
An ostomy coupling fastenable by a deformable locking member, the coupling comprising:a first coupling member comprising a deflectable seal wing extending around a coupling aperture of the first coupling member; a second coupling member comprising a seal seat surface extending around a coupling aperture of the second coupling member, the seal seat surface tapering with a curved taper in a direction towards the first coupling member when the coupling members are in an assembled condition; and a deformable split ring locking member being carried on one of the coupling members for releasably fastening the coupling members together, said deformable split ring locking member being deformable so as to expand upon pushing said first and second coupling members together into an assembled condition and thereafter resiliently contract for locking said assembled first and second coupling members together, said assembled members being separable upon expansion of said locking ring; wherein, in use, when the coupling members are in said assembled condition, the deflectable seal wing is deformed into a curvature to bear against the curved taper of the seal seat surface so as to form a seal.
