Sealing device (1) for a lead-through of a pipe (2) or the like through a wall, ceiling or floor into or out from a room, comprising a disc-shaped part (3) with a through hole (3c), arranged to be permanently installed between the sur face of the wall, ceiling or floor, alternatively between two surface layers of the wall, ceiling or floor, where the through hole (3c) is arranged to accommodate the pipe (2) to be led through, and where the disc-shaped part (3) is essentially impermeable to liquids. The invention is characterized in that the disc-shaped part (3) comprises an elastic flexible sheet material (4) arranged in the through hole (3c) and impermeable to liquids, which sheet material (4) is tight-f ittingly fastened to the disc shaped part (3) and covers the whole through hole (3c) except for an opening (4a) whose largest diameter is less than the smallest outer diameter of the pipe (2), whereby the sheet material (4), because of its elasticity, seals the lead-through of a pipe (2) which runs through the opening. |
