A PTC heating device for introduction into a receiving pocket of an electric heating device includes at least one PTC element, a conductor track that is electrically connected to the PTC element, and insulating layers that are abutted in a thermally conductive manner against the PTC element. A frame-shaped casing joins the at least one PTC element, the conductor track, and the insulating layers as a unit. The frame-shaped casing has a leading frame member with elastic guide tabs which, in an initial assembly state, project on oppositely disposed sides of the frame-shaped casing over the heat-emitting open surface respectively associated with them, which are inclined obliquely from the leading frame member in a direction of the open surface, and which are elastically pivotable. During heating device assembly, the PTC heating device is centered and guided by the elastic guide tabs when introduced into a heating rib of a heating chamber.
