Abstract
A rail clip is made by bending a metal rod with a length less than 18 times its thickness so that it has a substantially straight leg which lies substantially parallel to a railway rail in use of the clip and portions on both sides of this leg which press on the rail and a fixed surface, respectively. An arch connecting one of these portions to the leg rises at an angle of less than 45.degree. to the horizontal, proceeding along the rod away from the leg.
