1. An electric heating device comprising:
a housing with a partition wall which separates a connection chamber from a heating chamber for dissipating heat, wherein at least one heating rib protrudes from the partition wall in a direction toward the heating chamber and forms a receiving pocket;
a PTC heating device received in the receiving pocket, the PTC heating device including at least one PTC element and conductor tracks that are electrically connected in the connection chamber for energizing the PTC element with different polarities, the conductor tracks being connected to the PTC element in an electrically conductive manner, wherein 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 plurality of tongue and groove connections which extend in a direction of insertion of the receiving pocket and which effect heat extraction from the PTC element up to an outer surface of the heating rib.
