ABSTRACT:
A connecting element including an annular sleeve that has a self-supporting inner wall and a flexible outer wall, and a space between the inner and outer walls for introducing a preferably hardenable free-flowing filling medium into the connecting element to expand the connecting element radially outwardly to contact surfaces of adjacent pipe structures. A feed opening is provided in one of the inner wall and the outer wall to provide access to the space between the walls to permit introduction of the filler material. The connecting element is particularly suitable for sealing the joint between a multi-walled main pipe and a branch pipe extending from the main pipe.
