摘要：
A coupling arrangement has a coupling body and a helically shaped undulated metal pipe which has an end face extending along a screw thread of its undulation. A metal holding ring is mounted on the connecting part resting against the latter, where the outer diameter of the holding ring corresponds approximately to the outer diameter of the pipe, where the end face of the holding ring facing the pipe extends along a screw thread corresponding to the screw thread of the pipe, and where the holding ring is connected in the mounted position, fixedly to the connecting part by resting fixedly and tightly against the end face of the pipe.
