摘要

The system for connecting a flexible corrugated pipe (2) with a second pipe, especially a water supply pipe between a cistern and a toilet bowl, comprises a sealing sleeve (4) with ribs (12) on its inner surface which fit into the corrugations of the pipe. The sleeve has external ribs (18) with a triangular cross-section whose outer ends (18a) form a seal inside the second pipe.
