摘要

A coupling for coupling an ostomy pouch (5) to a pad (1) to be adhesively attached to the abdomen about the stoma of a user comprises two interengaging rings (7, 3), respectively attached to said pouch and to said pad about an aperture (2) for passage of the stoma through said coupling device into said pouch. The ring (3) attached to the pad (1) includes a peripheral bead (9) on the radially outer surface of the ring and the ring (7) attached to the pouch (5) is larger than the ring attached to the pad and includes a resilient lip (22) extending from the radially inner surface of said latter ring, the free end (23) of said lip facing towards the aperture in said pouch. The two parts of the coupling are engaged by fitting the ring on the pouch (7) over the ring on the pad (3) such that the lip (22) is deflected as it passes over the peripheral bead (9) and the free end of said lip becomes engaged behind said peripheral bead to hold the coupling secure. The coupling is disengaged by pulling on the ring attached to the pouch such that the resilient lip is caused to deflect back over the bead (9).
