ABSTRACT:
The present invention relates to a branch pipe connection for connecting a branch pipe to a lightly constructed underground sewage and drainage pipe. The connection includes a locking ring and a sleeve that are arranged against one another and can be tightened in their axial direction. The connection further includes a support flange. The locking ring has a slit by means of which the locking ring can be placed inside the underground sewage and drainage pipe through a hole made for the branch pipe from outside the underground sewage and drainage pipe. The pipe connection also comprises a sealing that is arranged to extend from the inner surface of the underground sewage and drainage pipe as far as the sleeve. A compact, dismountable connection for improving the ring stiffness of the underground sewage and drainage pipe is produced in this way.
