New anchoring device for arms of lamps and the like, of the type in which the arm is formed by two parts, a fixed external tubular, and an internal one, constituted by another tube or cylindrical bar, movable inside it, characterized due to the fact that at the end of the displaceable inner tube or bar, a bushing is connected, in which a plurality of radial blind holes are provided in its periphery, in each of which a coil spring is inserted, which at one end it rests on the bottom of the blind hole and on the other pushes a ball disposed in the hole itself, which tends to maintain it, partially and constantly, outside the housing.
