Claim:
1. A resilient railway rail fastening clip for fastening a railway rail to an underlying foundation, the clip being such that it can be deflected from a non-operative configuration to at least one operative configuration in which a toe portion of the clip can bear on a railway rail, the clip being made from a rod of resilient material shaped so as to have, proceeding from one end of the rod to the other end of the rod, firstly a substantially straight first portion, then a substantially bent second portion, then a third portion, then a fourth portion which is substantially U-shaped and forms the toe portion of the clip, then a fifth portion, then a substantially bent sixth portion, and finally a substantially straight seventh portion, the first and seventh portions of the clip forming leg portions, the longitudinal axes of which lie substantially in a first plane when the clip is in its non-operative configuration, the third and fifth portions lying between the first and seventh portions, wherein when the clip is in its non-operative configuration, the second and sixth portions extend substantially away from and above the first plane and at least parts of the third and fifth portions extend towards and above the first plane such that the longitudinal axes of the third and fifth portions lie substantially in a second plane, different from the said first plane, which second plane intersects the first plane at a first acute angle α, and the fourth portion extends substantially in or below the said first plane such that the longitudinal axis of the fourth portion lies substantially in a third plane which is different to the said second plane and intersects the said first plane at a second acute angle β, where 0°≦β<α.
