A device for the laying of pipes, conductors through apparatus walls with seals comprises a nipple with a threaded union and a polygonal shoulder for a tool attachment, as well as a sealing insert and a pressure screw. On the nipple (3) on the side facing away from the threaded union (4) is a tension release device (9). This consists of a short pipe (10) moulded coaxially on the nipple and a tapering tension device (11). The short pipe has fingers projecting axially. The tension device is a tension band consisting of a "hose position" that can be squashed or tightened with a screw. The short pipe has a cylindrical inner surface, a slender outer surface in the middle and a large diameter outer surface at the ends.
