Abstract
A molded connecting piece has two saddle-shaped pieces one of which carries a hole drilling or punching tool and the other of which is connected to a branch line. The two connecting pieces are interconnected by an annular channel so that, when they surround are attached to a pipeline and a hole is made in the line, the medium reaches the branch line from the pipeline through the hole, through the annular channel and to the branch line. Between the saddle pieces and the pipeline are heating mats by which a tight welding connection can be produced.
