OSTOMY APPLIANCE COUPLING RING CONSTRUCTION Abstract of the Disclosure A coupling for an ostomy appliance that detachably joins an ostomy bag to a faceplate capable of being adhesively secured to a patient's skin about a stoma opening. Each coupling ring is formed of flexible and resilient thermoplastic material, with one of the rings having an axially-extending frusto-conical neck portion and the other ring having a frusto-conical collar portion detachably receiving and sealingly engaging the neck portion. Primary latching is achieved in an annular zone spaced a substantial distance radially outwardly from the area of sealing engagement between the neck and collar portions, such latching action being provided by a shoulder extending about the outer periphery of one of the rings and a latching rib, defining a shoulder-receiving recess, extending about the outer periphery of the other ring.
