Abstract: The lamp has a lamp cap (10) with a metal shell (20), in which an insulator body (30) with a circumferential outer surface (31) between a first and a second end face (32, 33) is locked. Recesses (34) occur at the outer surface (31) at a cross-section (II--II). Between these recesses (34) the outer surface (31) has flattened portions (35), which enable the metal shell (20) to be deformed when the insulator body (30) and the shell (20) are assembled together, and to widen temporarily near the recesses (34).

Consequently, the projections (23) press clampingly in the recesses (34) of the outer surface (31), when the metal shell (20) is released, thereby tightly securing the insulator body (30) in the metal shell (20 ).
