Abstract
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.
