    摘要： A lamp bulb (1) made from glass is sealed at one end by a pinch (2). A base (5) is fastened on the pinch (2) by means of a metal spring (6). The base (5) has a holder (7) loosely adapted to the pinch (2). The metal spring (6; 26) is bent in a U-shaped fashion and comprises a base part (11) and two limbs (12, 13) which embrace the pinch, the fastening of the base (5) being accomplished by virtue of the fact that one limb (12) is aligned essentially parallel to the longitudinal axis, but simultaneously has a transverse extent accessible to spring forces, the transverse extent of this limb being stressed by the holder (7) of the base.
