To ensure contact of axially bent-back current supply leads, extending over plate-like base terminals of an elongated fluorescent lamp, and ensure electrical connection between the bent-aver ar bent-beck portions with socket terminal springs (9a, 9b), in spite of misalignment of the bases (3) at two opposite ends of the fluorescent lamp, the junctions or corners (1118) between the narrow wall portions (18a, 18b) and wide side wall portions (11a, 11b; 12a, 12b; 13a, 13b) of the end portion (4) of the base are set back from the position in a theoretical geometric rectangle or parallelogram to form relieved wide side wall portions. The relieved side wall portions extend axially over essentially the entire length of the end portion (4) of the base. The arrangement permits alignment tolerances, that is, limited relatively canted or twisted positioning of the bases, and insertion into aligned sockets, while ensuring reliable electrical connection between the lamp terminals and the socket connection elements (5a, 6b).
