The connector pipe (2) to retrofit into a branch opening (3) of an underground pipe (1) is provided at its end with a flange ring (4). This ring is larger than the branch opening, and has with several slits (5). As a result, the pipe end section with the ring is compressible and can be inserted into the branch opening where it serves as a shoulder against which connector pipe joint is tightened.
