An electric heating device comprises a housing with a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one PTC heating device protrudes as a heating fin in the direction toward the heating chamber. The PTC heating device comprises at least one PTC element electrically connected to conductor tracks in the connection chamber. A temperature sensor is connected, in terms of data, to a control device and is accommodated in a sealed manner in a temperature sensor receptacle which is formed in a wall delimiting the heating chamber. The temperature sensor is accommodated in a sliding manner in the temperature sensor receptacle. A support prevents the temperature sensor from sliding out of the temperature sensor receptacle and/or directly plugs a temperature sensor contact element of the temperature sensor in the connection chamber into a printed circuit board.

An electric heating includes a housing having a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one receiving pocket, protruding into the heating chamber as a heating rib, preferably tapering towards its lower and closed end, protrudes. A PTC heating element, including at least one PTC element and conductor tracks for energizing the PTC element with different polarities, is accommodated in the housing with the conductor tracks being electrically conductively connected to the PTC heating element and being are electrically connected in the connection chamber. A pressure element is received in the housing and holds heat extraction surfaces of the PTC element abutted against oppositely disposed inner surfaces of the receiving pocket. To reduce mechanical stress on the PTC element or an insulating layer and, while at the same time retaining the PTC heating element in the receiving pocket, at least one web acts in a positive-fit and/or force-fit manner on the pressure element.

The present disclosure describes a heating element for, e.g., an electrically drivable motor vehicle.
