Claim 0:
1. A PTC heating element for an electric heating device, comprising:
a casing that joins, as a unit, at least one PTC element, conductor paths that are electrically connected to the PTC element, and insulating layers that bear against the PTC element in a heat-conductive manner; and
contact strips which project over the PTC element and which are electrically conductively connected to the conductor paths for energizing the PTC element with different polarities, wherein
the casing forms a receptacle space that receives the PTC element, the conductor paths, and the insulating layers, wherein
the receptacle space, in a cross-sectional view, is defined by two oppositely disposed flat inner surfaces covering the PTC element, deformation segments adjoining the inner surfaces, and outer longitudinal edges of the casing, wherein
the deformation segments are provided, in a cross-sectional view, between one of the inner surfaces and the associated outer longitudinal edge, and wherein
the deformation segments are plastically deformed in a direction towards the receptacle space, opposite the inner surfaces and the outer longitudinal edges of the casing, and perpendicular to the flat inner surfaces of the receptacle space.
