An electric lamp with a base (6), which is structurally subdivided into an upper part (7) that retains the bulb and a substantially circular-cylindrical lower part (5) for external fastening, which lower part protrudes past the upper part, and the protruding portion (13) is embodied as a detent mechanism for the external fastening. The detent mechanism in each case includes an inward-facing detent protrusion (20) located on the outside, which is an integral component of the lower part, and a metal spring (24), located opposite the detent protrusion and cooperating with it, that is secured in the lower part.
