Plug-in pipe coupling for sealing off an inserted pipe end incorporates a sleeve unit and a gripping device for the end of a pipe inserted into the sleeve unit

摘要

A sealing element (13) seals a pipe's inserted end in a sleeve unit (2) containing an oscillating element (26,28) that moves in the sleeve unit prior to inserting the pipe's end and fastens tight in the sleeve unit after fully inserting the pipe's end. A separate device causes the element to oscillate, so that its oscillations can be observed or recorded.
