Abstract
Functional elements, particularly PTC heating elements, are braced in a hollow reception means, such as a profile tube. The reception means have two at least partly concave top wall areas facing one anther and flat sides of the functional elements and in this way permits a bracing of the functional elements, in that side walls of the reception means, extending substantially perpendicular to the concave top wall areas, are subject to the action of a pressing pressure. In the free space areas defined by the concave top walls can be fitted ends of attachment parts, such as metal lamellas, which are clamped in the same operation, according to the invention, during the bracing of the functional elements. This makes it possible in a simple manner to manufacture assembled devices, particularly electric heating devices.
