ABSTRACT:
The tubular electric incandescent lamp has at its ends (7,8) metal hoods (4), to which the current supply conductors (9,10) are secured. The metal hoods (4) are arranged in an insulator housing (5,6) provided with an opening (13), through which a contact member (11,12) extends to the exterior. The contact member (11,12) has a bifurcate part (19) which grips around the metal hood (4) behind a collar (17) at the said hood. The insulator housings (5,6) lock the contact members (11,12) against radial displacement. By the collar (17) and the insulator housing (6), the contact member (12) is undetachably connected to the metal hood (4). The lamp can be constructed so that the contact members (11,12) are displaceable in longitudinal direction between two extreme positions.
