Abstract
The electric lamp in accordance with the invention has a bayonet lamp cap (3) which is coupled to the neck-shaped portion (2) of the lamp envelope (1) by means of projections (7) and guides (8) co-operating therewith. The coupling is locked against displacement by means of a solidified mass (10). The co-operation between the cams (7) and the guides (8) is obtained by a rotation of the lamp cap (3) with respect to the lamp envelope (1) in counterclockwise direction until the cap abuts the envelope, the abutting stopping further rotation.
