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</SUB>) 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 (P 1 ) 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</SUB>). A half-cylindrical wall ( 11 ) permits the passage of the threaded rod ( 5 ).
