A locking device shaped like a pin but split up the center. It's usually inserted in a hole drilled through a nut and bolt and is intended to lock the nut in place so that it can't unscrew. After insertion, the legs of the cotter pin are bent around the nut to keep it in place.
A looped wire split pin, which holds objects together by having the ends opposite the loop spread apart, after insertion through a hole.
A cotter pin (also known as a cotter key or a split pin) is a metal fastener with two that are bent during installation, similar to a staple or rivet. Typically made of wire with a half-circular cross section, a new cotter pin (see figure, A) will have its flat inner surfaces touching one another for most of its length, so that it appears to be a split cylinder (figure, D). Once inserted, the two ends of the pin are bent apart, locking it in place (figure, B).
