Zipper

A zipper, also called a zip fastener, is a device for binding together two edges of fabric or other flexible material using interlocking teeth drawn together by a sliding tab. The modern device grew out of a fastener patented in 1892 by the American inventor Whitcomb L. Judson, and it later took its familiar name from a 1923 line of rubber boots that could be closed with, in the manufacturer's words, a single zip of the hand, after which the hookless fastener itself became known as the zipper.
