Abstract

An electric heating device for a motor vehicle includes at least one PTC heating element with contact metal sheets extending substantially parallel to one another and accommodating between them at least one PTC element, and a printed circuit board. The printed circuit board has formed therein at least one opening through which a contact tongue projects. The contact tongue serves to establish an electric connection between the PTC heating element and the printed circuit board. For providing an electric heating device having a compact structural design, a punched-out connection piece connected to a conductor path of the printed circuit board in an electrically conductive manner. The connection piece defines a fixing portion which rests on the printed circuit board, and also defines and at least one spring tongue projecting into the opening.
