Method and arrangement for the fastening of a corrugated pipe and a pulling plug to each other as well as corrugated pipe and pulling plug therefor

摘要

A method for attaching a pull-out stopper (20) to a locking end of a corrugated tube (10) is specified in order to lay a corrugated tube in a duct or the like, the corrugated tube (10) having a locking device (11) at least at its locking end, and the pull-out stopper being fitted with a complementary latching tab device (20b) which is fixed to the locking end of the corrugated tube having the locking device. In particular, the locking device in this case has an insertion groove (11a) which runs inwards in the longitudinal direction from the locking end, and a stop groove (11b) which is connected thereto at right angles and runs along the circumference of the corrugated tube. The latching tab device has at least one latching tab (20b) on the pull-out plug (20), which is inserted into the locking end of the corrugated tube (10) such that the latching tab (20b) is guided in a sliding manner along the insertion groove (11a) and the stop groove (11b). Furthermore, the locking device has a bayonet-fastener type locking groove (11c) which runs from the inner end of the stop groove (11b) in the direction of the locking end of the corrugated tube, but ends before the locking end.
