ABSTRACT:
The present invention relates to a branch pipe connection including 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 is of such a flexible material that the locking ring can be placed inside a pipe or the like through a hole made for the branch pipe from outside the pipe or the like, although the smallest outer diameter of the flange of the locking ring is larger than the largest diameter of the hole.
