A railway rail fastening clip (1) suitable for holding down a railway rail (2) is formed from a rod of resilient material bent so as to be approximately M-shaped in plan, the clip (1) being such that, when it is bearing on the flange of a rail (2), the longitudinal axis of a part (14) thereof, which interconnects inner legs (13, 15) of the M, lies in a reference plane which is substantially parallel, but not identical, to a plane containing the longitudinal axes of outer legs (11, 17) of the M. such clips (1) are used with an anchoring device (5), which, as the clip (1) is installed therein, deflects the outer legs (11, 17) downwardly with respect to the inner legs (13, 15), so as to place the clip under stress.
Un crapaud de fixation (1) de rail de chemin de fer, servant à retenir un rail (2), est composé d'une tige d'un matériau élastique pliée de façon à présenter une forme plus ou moins en M, le crapaud (1) étant conçu de façon que lorsqu'il prend appui sur la flasque du rail (2), l'axe longitudinal d'une partie (14) du crapaud, qui relie réciproquement les tranches internes (13, 15) de l'M, se trouve dans un plan de référence pratiquement parallèle, mais non identique, à un plan dans lequel se situent les axes longitudinaux de tranches externes (11, 17) de l'M. De tels crapauds (1) sont utilisés avec un dispositif d'ancrage (5) qui, lorsque le crapaud (1) y est installé, dévie les branches externes (11, 17) vers le bas par rapport aux branches internes (13, 15), de façon à soumettre le crapaud à une tension.
