Abstract

The invention relates to a corrugated pipe connection, in which one end of a corrugated pipe (1) is inserted into a connecting part and fitting (2) and is fastened therein by means of fixing elements. An annular ancillary element (4) is located upstream of the connecting part (2) on the jacket of the corrugated pipe (1). Sealing gaps are configured between said ancillary element (4) and the corrugated pipe (1) and between said element and the connecting part (2), said gaps acting as labyrinth seals and preventing the infiltration of high-pressure water.
