A mounting assembly for an ostomy pouch. The assembly includes a body flange having an adhesive coating on one side adapted to be adhered to the peristomal skin surface of an osteomate. Diametrically opposed loops project from the edge of the flange and form pockets. Also included is an ostomy pouch having a stoma receiving opening surrounded by a stiffly flexible ring having diametrically opposed loops that cooperate with the pockets on the flange loops. An adhesive coating is provided on the flexible ring and there is a mechanical interlock between the ring and flange. When the loops on the flexible ring are aligned with the pockets on the flange the flange and ring may be adhesively interlocked to attach the pouch to the body flange.
