Abstract
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 heating rib protrudes in the direction toward the heating chamber and forms a receiving pocket. A PTC heating device is received in the receiving pocket and includes at least one PTC element and conductor tracks which are electrically connected in the connection chamber for energizing the PTC element with different polarities and which are connected to PTC element r in an electrically conductive manner. A profile member is provided between the PTC heating device and an inner side of the receiving pocket and is connected to the receiving pocket by way of a tongue and groove connection which extends in the direction of insertion of the receiving pocket.
