Abstract
A tapping saddle for a plastic main pipe carrying a medium includes a stub having a central axis, a saddle piece, and a drill. The drill is configured to be moved axially in the stub. A heating element geometry, which is used for welding the tapping saddle to a main tube outer circumference, is arranged on an inside diameter of the saddle piece. The heating element geometry has a winding having an outer winding region and an inner winding region. In the inner winding region, the winding extends in meandering loops along a circle concentric with the central axis of the stub.
