ABSTRACT:
An arrangement for connecting pipe pieces, particularly pipe pieces of exhaust systems of motor vehicles, is provided with end sleeves each fastened to the ends of the pipe pieces and pointing in each case to the other pipe end. In the interior of the end sleeves, bellows are arranged, the ends of the bellows being in each case connected with a pipe piece. A stranded spring extends helically along the outer circumference walls of the end sleeve. On the exterior side, the stranded spring is at least partially covered by protection sleeves which are provided with corrugations adapted to the course of the helical line and in whose interior the stranded spring is guided. The protection sleeve is connected with the end sleeves and the ends of the stranded spring are connected with the protection sleeves or the end sleeves.
