ABSTRACT:
A two-piece ostomy appliance is disclosed, one component being a collection pouch and the other an adhesive faceplate for peristomal attachment to a patient. The two components are provided with coupling rings for mechanically and detachably joining them together. One of the rings has a bead-providing collar and a rocking wedge body as disclosed in U.S. Pat. No. 5,185,008. The other ring is of channel-shaped cross section having spaced concentric inner and outer side walls each provided with ribs positioned in direct opposition and extending into the channel along a single plane normal to the axis of that ring. In a preferred embodiment, the rib of the outer wall is interrupted to provide at least one wide notch or recess and an integral pull tab projects radially outwardly from the outer wall at the location of the notch for initiating either partial or complete separation of the rings during use of the appliance.
