摘要

An electric lamp (1) comprising a gastight lamp vessel (3) mounted on a base (19). The lamp vessel is surrounded by a sleeve (25) having an open end (28), the base is connected at the open end of the sleeve. An essentially tubular shaped connection part connects the base to the sleeve without the use of cement. There to the sleeve extends through a first opening (32) of the connection part and engages with a radially, outwardly bulging portion (29) a radially, inwardly extending portion (31) of the connection part.
