An ostomy appliance is provided in which a thermoplastic convex pressure ring also functions as a belt-attachment ring. The pressure ring is directly and sealingly secured on its convex side to an adhesive faceplate and is also directly and sealingly secured on its opposite side to a collection pouch. Only two annular attachment zones, either in the form of heat seals or adhesive seals, are required to secure the pouch, pressure ring and faceplate together.
