DETAILED DESCRIPTION

(7) FIG. 1 shows a schematic representation of a radiator element 100, with a resistor segment 1. The electrical resistor 1, of any shape, material characteristics, power and dimension, is electrically connected at each of the terminal poles to a tubular diffuse radiator 3, preferably of aluminum of any form and dimensions, directly by means of crimping 2. The supply lines 7, preferably made of insulated copper braid wire, are connected for the electrical connection via wire ferrules 5, which fit into the aluminum tubes of the diffuse radiator 3, by means of crimping 2.1, so that no reactions between aluminum tubes 3, and copper wire cable 7, can occur.

(8) FIG. 2 shows a schematic representation of a radiator element 100 for installation in a heating profile. Braided glass sleeves 4 are put over the supply lines 7 and over the crimping 2.1 of the radiator 3 for electrical insulation, over which an aluminum tube 6 is arranged, which provides the necessary distance when the radiator element is incorporated into an application. The aluminum tube 6 is fixed to the aluminum pipe 3 of the radiator by pinching or crimping (not shown) and protected from displacement. In a further embodiment, the radiator 3 is formed solid.
