The invention relates to an electric heating device, in particular as an additional heating device for a motor vehicle, comprising an open housing, in which a layer structure, which has at least one radiator element, at least one heat-generating element and at least one PTC element, and at least one elastic element, which holds the layer structure in a pre-biased manner, are accommodated. It is anobject of the invention to propose an electric heating device of the type mentioned above, the layer structure of which can be easily mounted in a housing. According to the scheme of the invention, the elastic element is movably accommodated in the shell; the elastic tongues are arranged in a staggered mode in the moving direction. Wherein the elastic tongues are provided with elastic tongue receptacles formed by the housing and contact surfaces arranged adjacent thereto, which contact surfaces extend beyond the elastic tongue receptacles towards the layer structure, and wherein the elastic tongues contact the contact surfaces in order to pre-bias the layer structure.
