A railway rail-fastening clip is made by bending a resilient rod at least 0.8 cm thick in a first operation to give it first to fifth portions in direct succession. The first portion(1) is straight leg, the second a reverse bend, the third being(3) beside the first and the whole being such that in a particular position, with the first portion horizontal, in a plan view the third and fifth portions(5) appear to be in opposite sides of the axis of the first portion(1).
