Abstract: An indicating device (31) of a highly permeable material is detected by emitting and receiving a magnetic field, wherein two coils (1,2) are caused to emit a high-frequency magnetic alternating field, and a first one of the coils (1) emits an alternating field with a frequency (f.sub.1) different from the frequence (f.sub.2) of the field emitted by the second one of the coils (2), and at least one difference and/or sum frequency n.multidot.f.sub.1 +m.multidot.f.sub.2 occurring by intermodulation by means of the indicating device (31), where n and m are positive or negative integers, is caused to be received by one or several coils (9). A third low-frequency magnetic alternating field is caused to be emitted in said zone with a frequency (f.sub.3) substantially lower than the frequencies (f.sub.1,f.sub.2), which low-frequency field has a field intensity sufficiently high, independently of the fields with the frequencies f.sub.1 and f.sub.

Abstract: A ring surrounding the clip which secures the body of an LED diode lamp to a bracket is provided with inner longitudinal grooves which reduce the thickness of the wall of the ring and confer thereto an elasticity which is sufficient for permitting its engagement on clips of different diameters. The manufacture of diode lamps does not provide the bodies of these lamps with very precise or consistent diameters, so that relatively important variations of these diameters can occur, which have an influence on the diameter of the clip when engaged on the lamp. Owing to the present arrangement, diode lamp holders can absorb such variations of diameter of the lamps, and still be secured to a panel or other structure by the ring of the invention.
