Abstract
A pull tab for zippers is formed by a cord having a cord retaining member attached to one end of the cord and a plug attached to other end of the cord. The cord retaining member has an internal cavity, a first aperture on a proximal end next to the cord and a second aperture on a distal end. The cavity and first and second apertures are sized so that when the cord is wrapped around the plug, the plug fits through the second aperture and cavity but does not fit through the first aperture. The pull tab is assembled by feeding the plug through a zipper tab and then the first aperture, the cavity and the second aperture, wrapping the cord around the plug, and pulling the cord to force the plug with the cord wrapping back into the cavity.
