gur connection of two pipe ends are known; so-called Iiuttenrlnge used, which usually consists of Made of rubber and with a singing bead on both sides are provided. To get such a Luttenring on the Pulling up pipe ends is a high possibility of expansion of the RinggfLn radial direction required. on the other hand but must the rings against! Anrelssen when pulling and sufficient against mechanical influences in the pulled-up state be secured. The fabric inserts used for this purpose have so far not been satisfactory because the fulfillment of the one necessity was only possible at the expense of the other. Also employees with diagonally placed wessel or jersey * Attempts did not lead to a satisfactory result.

The hiring consists in the fact that fabric inserts are used in the manufacture of lute rings made of rubber, one of which ends perpendicular to <i ^ n annular bulges, in the pulled-up state of the hinge in the bend of the pipe axes, threads do not allow behiaing and thus the ring give annoying firmness while the other semkreeht
