The lead-through body comprises a casing (2) with elastic fire retardant foamed material (4) disposed therein, which, compressed transverse the longitudinal axis of the casing, is kept in the casing and sealingly surrounds the conduit or conduits. The casing is formed with an external helical thread (3). |
