Shockwave-absorbing gastight lead-through for one or more conduits (5) through a building component (1), e.g. the wall of an air-raid shelter. The lead-through is preferably arranged in a through hole (2) made in the building component (1) after the finished fabrication of the latter, and in one embodiment includes a prefabricated elastic body (3) of fire-proof foamed material, which sealingly encloses the conduits (5), and a stop plate (4) clamped in the hole and having holes (10) for the conduits (5), said plate engaging against the side of the elastic body (3) facing away from pressure. |
