Device to lead gas pipeline or cable through outer wall of building

摘要

The device to lead a gas pipeline (1), a cable, or similar through an outer wall of a building (2) has a tube (3) and at least one nut (8) to tension a movable flange (9) axially against the tube. The nut is accommodated on a tension device that can move axially relative to the tube and can be fixed towards the tensioning direction. The tensioning device is a threaded tube (6) with an outer thread that can slide on the first tube, in which the nut engages with a thread corresponding to it.
