ABSTRACT:
A pull tab of the zipper head is composed of a pull piece and an elastic piece. The pull piece has a beam, a hook, and an insertion slot located between a fastening end of the hook and the beam. The hook has an open end. The elastic piece has an inner body, an outer body, a curved portion, and two urging portions. The elastic piece is engaged with the pull piece such that the inner body is located in the insertion slot, and that the open end of the hook is sealed off by the outer body, and further that the curved portion is located across the beam, and still further that the two urging portions urge the beam. The elastic piece is thus securely engaged with the pull piece.
