Abstract

A supply lead (7) for a halogen incandescent lamp is bent in a U-shaped fashion and comprises a base (15) and two limbs (16). The ends of the limbs engage in the end region (6) of the luminous element by means of hook parts (20). A section (11) at the end, on the side of the luminous element, of the associated foil is folded back and forms a fold (12) in which the base (15) is held mechanically.
