The capped electric lamp has a quartz glass lamp vessel (1) having first and second neck-shaped portions (2, 3) with respective seals (4, 5). A glass envelope (9) surrounds the lamp vessel and is secured thereto. A clamping member (20) surrounds the envelope in a clamping manner. A fixation member (32) of a lamp cap (30) is welded to the clamping member. The clamping member (20) is an undulated metal body, the crests of its creases constituting regions (22) which are spaced from the envelope (9) and in which welds to the fixation member (32) are made. Its troughs constitute clamping zones (21) which hold the envelope. The clamping member (20) allows for the application of a relatively wide envelope (9), which may enter the lamp cap (30).
