Abstract

To facilitate manufacture, assembly, and save material, a halogen incandent lamp (1) is secured to a plastic base (6) by a carrier or attachment element (3) which is formed of a single unitary element in form of a collar or cuff (4) of essentially rectangular cross section, surrounding the pinch or press seal of the lamp. The cuff is formed with internally projecting spring elements (17) in the form of flaps or the like, which are formed with notches engaging ribs (19) or similar suitable projections formed on the pinch seal of the lamp. First and second side walls of the essentially rectangular, in cross section, cuff or collar portions overlap, and the side walls are connected together by interengaging projections and slits, bent over at the corner of the rectangular cuff or collar portion.
