Abstract
A fluorescent bulb retaining spring (6) comprises a one piece, sheet-metal stamped and bent part, entirely and seamlessly comprised of one material. The retaining spring (6) can be produced especially simply from one rectangular piece of sheet metal of substantially uniform thickness, with all functional parts and functional regions created by cutting out spring tongues and bending them outwardly from the sheet. Connecting legs between a bulb retainer portion (9) and a fastening portion (8) form an annular region which is closed in force-locking fashion by a crimped connection (29, 31, 32), which can be produced in automated fashion as part of the stamping and bending operation.
