Abstract: There is disclosed a device for fixing a U-shaped end of at least one spring for supporting a cushion for a seat, to a seat frame of the seat which includes opposing frame sections, one of the frame sections being formed from a shaft, and the spring being stretched between the frame sections. The device comprises a collar fitted over the shaft and a retainer including a body having a geometry of similar figure with the collar and fitted over the collar on the shaft, and at least one pair of first and second spring engagement pieces provided at both edges of the body. A first axial region and second axial region of the U-shaped end of the spring are engaged with the first piece and the second piece, respectively, whereby the end of the spring is fixed to the shaft through the device.
