Abstract
To minimize trauma after surgery, a clamp is employed to sealingly engage specially configured coupling rings mounted on the adhesive faceplate and the collection pouch, respectively. Each of the coupling rings includes a radially extending annular projection. The circular clamp is designed to surround the coupling rings and receive the projections within an annular recess. The projections and recess have oppositely oriented camming surfaces which cooperates to draw the coupling rings toward each other as the clamp is tightened. The clamp is locked by a toggle clasp connected by a living hinge, a pin and socket arrangement, a serrated clasp or a change purse type clasp. An adaptor can be employed so that the clamp can be used with a pouch with a conventionally configured coupling ring.
