Device for connecting a branch pipe to a sewer pipe and sewer pipe connection system

摘要

The pipe connection (12) and frame (14) are of single piece construction. The frame and the channel pipe are connected by a screw (60,67). The screw has a shaft (64) divided into three longitudinal sections (66a-c) and a screw head (62). The first longitudinal section (66a) adjacent to the screw head is four-sided and the connecting second longitudinal section (66b) is threadless. A sealing device (48) is arranged around a side of the frame facing the channel pipe (40). The frame on its side facing the channel pipe has an all-round groove (26) in which the sealing device (38) is arranged.
