An adhesive ostomy coupling comprises first and second coupling parts each having a respective orifice. The first coupling part includes an upstanding wall for entering the orifice of the second coupling part. The second coupling part includes an adhesive faceplate for adhering to the first coupling part outside the upstanding wall. The upstanding wall and the faceplate form an interference fit at a position corresponding to the inner periphery of the adhesive, to protect the adhesive from effluent attack. The upstanding wall has an undercut for interlocking with the adhesive faceplate of the second coupling part. The upstanding wall also acts as a guide to prevent mispositioning of the pouch when mounting the adhesive faceplate on the complementary flange.
