Abstract

An integral zipper slide and guard. The integral slide and guard is formed as a single unit, thus alleviating previous problems of attachment of zipper guards to zipper slides. Moreover, the unitary structure of the zipper slide and guard permits a one-step molding operation, thus providing inexpensive manufacture.
