ABSTRACT:
A resilient fastener for fastening a rail on its support, comprising a flexible blade of constant thickness having a longitudinal edge to be disposed parallel to the axis of the rail and applied against the rail flange. The blade has two orifices spaced from the longitudinal edge and arranged so that they are situated above the rail support and close to the edge of the rail when in fastening position. The longitudinal edge is curved to a convex shape presenting a substantially cylindrical surface of which the directrix is a curve inscribed between the warped shape assumed by the blade when loaded in its center and the arc of a circle passing through the blade center and the centers of the orifices.
