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 socket in the top surface of the cord retaining member, and a plug attached to other end of the cord. The plug has a shape corresponding to the shape of the socket, so that the plug can fit securely within the socket, thus, forming a loop with the cord. A slidable locking device is placed around the cord, the locking device having an interior cavity corresponding to the shape of the cord retaining member, such that placing the plug into the socket and sliding the locking device over the cord retaining member locks the second end of the cord to the cord retaining member. In a method for manufacturing the pull tab, the plug and cord retaining member are continuously overmolded in one piece on a length of the cord, and then cut into pieces to form completed pull tabs.
