<p>A device for the fire-constraining bushing of cables (10) or the like through a wall opening, having a supporting frame (1), which is anchored in the wall (2), for holding packing pieces (3) which are produced from material which swells under the influence of heat and are constructed with in each case one channel (4) which is used for holding a cable (10). In this case, the cables (10) are surrounded in the associated packing piece (3) by a slotted sleeve (12), which is manufactured from insulating material and projects beyond the packing piece (3) at least on one side. <IMAGE></p> |
