Abstract: A fastening device for a rail to a cross tie comprising a resilient, double C-clip and an appropriate holder having a passage in which the loop-like portion of the clip can be supported for producing the fastening force, wherein the clip portion bearing on the rail foot extends by at least one free end beyond the edges of the rail foot and wherein on the side facing the rail the holder has faces located in the path of at least one free end of the clip, when the latter is bent too far outwardly for releasing the foot of the rail and a holder and a clip for use in said fastening device.

Abstract: A method of making a resilient double C-shaped clip for securing a rail on a support, wherein in advance of the heat treatment the ends adapted to cooperate with the support and with the foot of the rail are bent towards one another in the direction of the fastening force to such an extend that they are offset with respect with one another over a certain distance in relation to their position when the ready clip is free of load and wherein after the heat treatment the clip is subjected to a series of permanent deformations, each effected by imposing a permanent deformation force on one end of the clip while the other end is held in fixed position, such that upon a continued deformation there would be no increase or only a very small increase of the load, and the clip being relieved of load after each deformation.
