Zusammenfassung:The connecting flange (5) is fixed onto the corrugated pipe (1) by means of an elastically flexible securing ring (2) with changeable external diameter and fitting into a cavity in the flange and inserted into one of the corrugation troughs (3) near the end of the pipe. The connecting flange has a slightly larger bore-hole (6) than the outer diameter of the corrugated pipe; the bore hole's diameter is smaller than the external diameter of the pipe. The cavity in the connecting flange consists of a peripheral groove (7) extending radially outwards from the bore-hole. The groove-edge facing the end of the piping has a slightly larger diameter than the external diameter of the securing ring.
