ABSTRACT:
A heating element for placing on a pipe or nozzle comprises a current-carrying conductor connectable by means of connecting leads to a power supply. Each of the connecting leads has a terminal contact piece which can be engaged with a contact surface of the heating element. The contact piece can be clamped against the heating element by means of a clamping device. The contact piece rests loosely on the contact surface and the clamping force of the clamping device acts in a substantially normal manner to the contact surface and clamps the contact piece against said contact surface.
