An elastic wall lead-through for pipes and supply lines, which is both sealed and soundproofed, and which has a hose-like elastic portion (11) that passes through the outer tube (8), and is connected at one end (18) with the outer tube (8) and on the opposite side (19), indirectly and rotatably via a rotary part or a clamping disc (20). By actuating the rotary part or clamping disc (20) a torsional seal (15) is achieved by the fact that the elastic part, which is preferably designed as a hose-like sealing surface, is rolled around the pipe or supply line which is to be fed through. Such a wall lead-through has the advantage that it simultaneously provides a seal and can withstand tractional forces. Closure of the openings in, for example, partition walls or casings is achieved in basically the same way and manner, except that in this case the hose-like elastic portion is twisted, so that the elastic part is tightly applied against the wall, thus providing the desired sealed closure. Such a closure can for example be used advantageously for bottles, but also for the sealing of clothes for sailors, anglers and similar, as well as a connection element for garden equipment and tools. In the same way as for pipe lead-throughs for input and output lines, the device described can also be used to exceptional advantage for cables and conductors for electrical equipment such as suction cleaners, telephones, typewriters and similar, especially as here a simple and very effective traction-resistant connection can be made.
