Abstract

The present invention relates to a method of manufacturing an electric heating device, comprising a housing in which a heating block is held with the pretensioning force of at least one spring element located approximately at the same level as the heating block in its post assembly position and which defines opposite housing apertures between which the heating block is exposed, wherein the heating block is introduced into a housing part and the heating block is enclosed in the housing by another housing part. The spring element is brought into its assembled position and pretensioned when the housing is being closed to enclose the heating block.
