ABSTRACT:
An electric lamp has a lamp vessel provided with a seal, fixed to a first end of a metal sleeve. In a second end of the sleeve an insulator body through which a contact member extends is rigidly secured. To that end the inner channel of the sleeve has a constriction cooperating with the insulator body at a second end face thereof, and an inward projection from the sleeve into a recess in a side face of the insulator body. The recess extends to a first end face of the insulator body. The lamp is of an easily producible construction.
