摘要：
A rail clip consists of a bent rod having, proceeding from a first end of the rod to the other end, a first portion which is straight, a second portion which is a reverse bend, a third portion beside the first portion, a fourth portion which is a reverse bend and finally a fifth portion beside the first portion. When the clip is in a defined position a section of the fourth portion lies vertically above and crosswise over the axis of the first portion and when the clip is viewed from above the third and fifth portions appear to be on opposite sides of the first portion. On the under-side of the third portion is a step having a rising face which faces away from the first end of the rod. This face co-operates with a stop on a seat for the third portion of the clip, to prevent unauthorized removal of the clip. The stop and seat are on an anchorage which provides a passageway, into which the first portion of the clip is driven, parallel to the length of the flange of a railway rail on which the fifth portion of the clip bears.
