bitch hook
noun
an all-purpose quick-release hook for use with a tractor and chain CANADA- The name “bitch hook” comes from a hole at one end of a slot in the long, flat central part of the device. A chain may be pulled through the hole, slide down and catch. When it is pulled back up to the hole, it releases quickly. — Lewis Poteet, Talking Country, p. 23, 1992
