ABSTRACT OF THE DISCLOSURE. To improve shock and vibration resistance and heat dissipation of an attachment element (l) coupling the pinch seal (3) of a halogen incandescent lamp (2) to a plastic base (6), the attachment element is formed of two identical half-sections, surrounding the pinch seal in the shape of a cuff (4) and connected to a flange or skirt by an intermediate heat dissipation and shock absorbing portion (7, 11, 12, 13, 14). Preferably, the intermediate portion forms a connecting section, which can be bent into U or double U configuration off the upper region of the flange or skirt portion (8a, 8b), to provide a large heat radiating surface while retaining the pinch seal of the lamp between undulating sheet-metal portions. Preferably, the attachment element is made of unitary sections of high-quality specialty steel.
