A three piece metal tie comprises a head 10, an elongate flexible strap 11 attached to the head 10, and a locking ball 12 captively mounted within the head. The ball 12 is inserted into the head 10 through an opening 19 in its bottom wall 14, which is subsequently closed by the strap 11 once the latter is attached to the head 10. The strap comprises a U-shaped head engaging portion 24 which engages the bottom wall 14 of the head. Oppositely directed barbs 22,23, disposed on respective arms of the head engaging portion of the strap, interengage through the opening 19 in the bottom wall 14 of the head, and thus positively lock the strap 11 to the head 10. <IMAGE> |
