In order to heat flanged shafts 1 of different lengths a heating inductor which comprises a pair of parallel conductors bridged at their ends by bridges is made in two parts 2 and 3 which are axially slidable relative to one another to adjust the length of the inductor and are mechanically and electrically connected together over the region of overlap by connecting elements. Each connecting element comprises a U-shaped clamp 7, 8 and a contact blade 5 positioned between the conductors. The fixed conductor part 2 has a reinforcing copper section 6 soldered along its length and the movable conductor part 3 has a wedge-shaped copper element 4 soldered to it over the area of overlap. The screw 7 traps the element 4 blade 5 and conductor part 2. The length of the blade 5 is between one and one and a half times the width of conductor 3. Both conductor parts are hollow rectangular copper tubes divided by a longitudinal baffle which directs coolant. Bores may be provided on the conductors for heat concentration.
