摘要

The invention relates to a fire-prevention device (1) for conducting cables or pipes through a passage in a wall or ceiling. Said device comprises a housing (2), whose interior contains at least one fire-prevention element, which in the event of a fire can increase in volume in order to fill at least part of the housing (2) temporarily. The fire-prevention device (1) comprises at least one mounting element (4), which is designed to be adapted to a clearance between the housing (2) and the passage. The invention also relates to a fire-prevention cable duct (101) comprising a housing (102) that is open at both ends and that has an inner chamber. The housing (102) is provided with a material that fills at least part of the inner chamber when heated and also an insulating material, in the form of a block (107), which fills only part of the housing (102) and is provided on one or both sides of the opening in said housing (102).
