<p>The invention relates to an ostomy coupling comprising two annular coupling parts (1, 2) and a locking ring (3), where the two coupling parts (1, 2) are attached to an adhesive disc or a collection receptacle or a closing plug, respectively, the first coupling part (1) comprising a collar (5) having a radially outwardly projecting annular edge (6) for forming a groove (7) with an in radial direction innermost groove section (7a), and an annular recess (11) positioned in its in radial direction inner side, and the second coupling part (2) comprising an axially projecting part (17) having an annular radially outwardly projecting beak (18) being capable of engaging with the annular recess (11) in the first coupling part (1), and where the locking ring (3) has an annular in radial direction inwardly projecting protrusion (26), and that 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 that the annular recess (11) in the in radial direction inner side of the first coupling part in axial direction is closer to the attachment surface (4a) of this coupling part to the collection receptacle, the closing plug or the adhesive disc than the annular innermost groove section (7a).</p> |
