Abstract
A securing device for a railway rail includes a fixing rod having a first end in the form of a spring head which bears on the shoe of the rail. The rod extends through a shim and has a second end is configured like a hook and is held in an anchoring sheath embedded in a support. The anchoring sheath includes a shoulder for tensioning the spring head under the shoe of the rail after the rod has been rotated by a half turn. The tensioning of the rod also results from the slope of the upper surface of the shim which extends upwardly and continues the slope of the shoe of the rail.
