ABSTRACT:
An ostomy coupling including two annular coupling parts and a locking ring. Each coupling part is attached to one of an adhesive disc, or a collection receptacle or a closing plug. The first coupling part has a collar with a radially outwardly projecting annular edge. The edge forms a groove with an in the radial direction innermost groove section. An annular recess is positioned in the radial direction inner side of the collar. The second coupling part has an axially projecting part with an annular radially outwardly projecting beak capable of engaging the annular recess in the first coupling part. The locking ring has an annular protrusion that projects inwardly in the radial direction. The locking ring is positioned in the groove of the first coupling part, so that its innermost diameter when it is in its locked position, is smaller than the largest beak diameter of the second coupling ring, and the annular recess of the first coupling part is closer to the attachment surface of this coupling part to the collection receptacle, the closing plug or the adhesive disc than the annular innermost groove section.
