<p>A two-part ostomy coupling has a first part (10) which is a flat annulus (11) having inner and outer peripheral walls (12, 13). With the annulus these walls define a shallow channel. The coupling has a second part formed by a second flat annulus with radially inner and outer rims (26, 27) formed by respective flexible peripheral elements of plastics material. The first and second parts are constructed so that the second part is a push fit into the shallow channel defined by the first part (10). The second part may be an annular member having a flexible resilient strip (27) extending inwardly from its radially inner edge and an element (26) extending from its radially outer edge which can engage under a rim portion of the said outer peripheral wall (13). Alternatively the second part may be an annular member having a flexible resilient strip extending outwardly from its radially outer edge and an element extending from its radially inner edge which can engage under a rim portion of the said inner peripheral wall.</p> |
