Abstract
A two-piece ostomy appliance with a low profile coupling ring assembly in which the rings are moved transversely rather than axially into and out of interlocked condition. The faceplate ring has an upturned flange along its lower border and the pouch ring has a downturned flange along its upper border, with the flange of each ring defining a channel for receiving a peripheral portion of the other ring for locking the rings together as they are shifted transversely (radially) into axial alignment. The configuration of each ring about the stoma opening thereof results in a preloaded annular seal when the rings are coupled together.
