Abstract
The invention relates to a device for holding one end of a helical spring and adjusting the tension of the spring. It comprises a plate (P.sub.1) provided with two series of holes (12, 13) spaced apart by a distance approximately equal to the diameter of the turns of the spring. The holes of one series are offset with respect to those of the other series. The plate (P1) is provided with a gripping and holding device (5, 8). The gripping and holding device comprises a threaded rod (5), one end of which is provided with a holding means (8). The threaded rod (5) engages in a tapped hole (15) integral with said plate (P.sub.1). A half-cylindrical wall (11) permits the passage of the threaded rod (5).
