Abstract
In a lamp according to the invention the use of cement for connecting the lamp cap (4) has been avoided by using a split metal ring (8). The neck-shaped lamp envelope portion (2) has recesses (13) in which projecting parts (12) of the ring (8) engage. The ring (8) has lugs (14) which at least initially press against the lower edge (3) of the neck-shaped lamp envelope portion (2). The ring (8) is secured to the lamp cap (4). During assembly of the lamp cap (4) the lugs (14) are deformed. A resilient force thereby induced in said lugs pulls the ring (8) in a direction opposite to the direction in which the lamp cap (4) was moved. As soon as the ring (9) is secured to the lamp cap (4), the resilience in the lugs (14) is of no further significance.
