1. A device for the sealed fastening of a pipe (2) in the opening of a pipe-supporting plate (3), comprising a sleeve (4) of flexible material, which sleeve is inserted in the gap between the pipe and the opening, bears against the pipe-supporting plate (3) by a flange arranged at the front, is thickened in its rearward part to form a bead exceeding the width of the gap and, under pretension, bears against opposite wall regions of the opening and of the pipe (2), the sleeve (4) being made of an elastomeric material and being provided in the region beyond the bead with an extension which has an internal diameter slightly smaller than the diameter of the pipe (2), characterised in that the opening conically widens in the rearward direction in the region of the axial extent of the bead (6, 7), and that the extension is a ring membrane (5). |
