<p>The present invention relates to a transit device for passing at least one elongate line (41) sealingly through an opening in a wall (10), said device comprising a clamping frame (11) and a number of blocks which together fill-out the frame (11). At least one of the blocks (5) has a through-penetrating channel (5) for receiving the line (41), wherein the block (5) is adapted to permit lateral insertion of the line (41) into the channel (51). The device also includes a separate tubular bush (1) made of elastic material. The bush (1) has a generally axial through-penetrating slot (3) in its wall, to enable the bush to be laterally fitted to the line (41), and has an outer cross-section which corresponds generally to the cross-section of the channel (51) in the block (5). The bush includes a plurality of radially separated layers (2), which can be separated from each other so as to adapt the through-penetrating channel (8) of the bush to the line (41).</p> |
