An ostomy coupling (10) is described in which a body-side coupling member (12) has walls (20, 22) defining a channel (24) for receiving the projecting annular formation (48) of the bag-side coupling member (14). A locating rib (26) projects from the floor of the channel, for co-operating with a groove (58) of the bag-side member to centre and prevent tilting of the coupling members. The bag-side member has a deformable wiper seal (56) which seals against the inner wall (20) of the body-side member, and wipes clean the wall (20) during assembly and separation of the coupling members. The outer wall (22) of the bag-side coupling member might be deformable, and a finger tab (82) might be provided to facilitate separation of the coupling members if desired. The bag-side coupling member (14) has an integral vent filter housing (60).
