Abstract
The sealing stopper has a lid (1) which is set onto a sealing part (2) with a conical sealing surface (8), leaving an annular space (15). At the bottom side of the lid rim (11) is a protrusion with a hemispheric recess, into which an end segment (4) of a chain (3) is set. In this manner, the latter is directly and tightly fastened to the sealing body and has no protruding parts on its upper side which could interfere with use of the stopper in the drain valve of a bathtub.
