Abstract

A tube arrangement, comprising a tube made of a polymer material which is provided with an embedded reinforcement. At least one tube end is slid onto a short metal or plastic pipe. A pipe clamp, especially a screw pipe clamp, secures the tube end onto the pipe. A retaining sleeve on the tube end secures the pipe clamp to the tube. This retaining sleeve is made of a polymer material and comprises a one piece molded part which is pushed onto the tube end. The retaining sleeve comprises the following components: a retainer ring with an inner diameter which is positioned over the outer diameter of the tube end; a clamp receiving element in the form of at least two axially extending retaining elements which are connected to the retainer ring at one end; a retaining collar at the other end of each retaining element; and a collar ring with an inside diameter connecting the retaining collars.
