Electric Heating Device

An electric heating device includes a housing which forms a heating element receptacle and at least one fluid channel A PTC heating assembly with a press-fit profile is inserted into the heating element receptacle. The press-fit profile forms a PTC receptacle in which at least one PTC element, strip conductors abutting thereon in an electrically conductive manner and, if appropriate, an insulation supporting the strip conductors in an insulated manner against the PTC receptacle, are provided. The housing is formed from an extruded profile and is held under a pretension in the heating element receptacle by deformation projections located between the housing and the press-fit profile. The deformation projections are formed by the housing and/or the press-fit profile.
