A metal fixing member is provided with tongues which are welded to the sleeve in a welding zone of the sleeve. A lamp cap of insulating material is connected to the lamp vessel in which the fixing member is fixed and which has contact members to which the current supply conductors are connected. The welding zone is provided with mutually opposing closing tags alongside the longitudinal slot.
