ABSTRACT:
For the purpose of repairing supply lines such as a waste-water pipe, a plastic hose has been developed which, in the clear state, has a diameter which is the same size as, or larger than, the diameter of the pipe in which it is to be inserted. This plastic hose is used to fix optical or electric cables against the inner wall of the pipe. For this purpose, the plastic hose is introduced into the waste-water pipe in a collapsed state, together with the cable, and is released when the desired positioning has been reached. The collapsed plastic hose will then regain its original shape and thereby fix the cable against the inner wall of the waste-water pipe.
