Abstract

The heating element is slidably fixed to a cylindrical part and consists of a longitudinally slitted metal tubular inner part (1) which has a good heat conductivity. The inner part has a cylindrical inner shape and a conical outer shell. The outer shell has a profile groove (3), in which an electric heating body is inserted. The outer shell of the inner part has axial slots (6), and the outer part (5) has holes (7), which in the clamped state, cover each other. A detracting tool can be inserted into the holes and slots, by means of which the outer part is slidable relative to the inner part, along the length of the slot (6) in the detracting direction.
