A capped electric lamp has a light-transmitting lamp vessel accommodating an electrical element and a lamp cap provided with a projecting contact pin (4). An indentation (15) is formed in the contact pin (4) to fix the current-supply conductor (5). According to the invention, the indentation (15) comprises a weakening portion (16) for weakening the current-supply conductor (5) during the manufacture of the electric lamp and comprises a fixation portion (18) for fixing the current-supply conductor (5) in the contact pin (4), wherein said weakening and fixation portion are substantially parallel to each other. Preferably, the indentation (15) comprises a narrow portion (17) between the weakening portion (16) and the fixation portion (18) which is relatively narrow compared with the weakening portion (16) and the fixation portion (18).
