Abstract
A railway rail-fastening clip, made by bending an initially straight rod, is approximately in the form of a letter e. The axies of all parts of the clip, except possibly the free end of the lower arm of the e, lie in a single plane. The rod may have a length less than 15 times the thickness of the rod. A retaining arrangement for the clip may have an opening in which lie the center arm and the upper arm of the e, the lower arm of the e pressing downwardly on the flange at the bottom of a railway rail. The opening may be in an electrically insulating bushing in a clip-retainer made of metal.
