ABSTRACT:
In a tie including an elongated tongue and a locking head having a movable pawl that is hinged at one side of an opening in the locking head across the opening from an abutment surface for locking engagement with a first set of ratchet teeth on one broad side of the tongue when the tip of the tongue has been inserted through the opening and teeth on the abutment surface for locking engagement with a second set of ratchet teeth on the other broad side of the tongue when the tip of the tongue has been inserted through the opening, and in which the side of the pawl including the pawl teeth converges toward the opposite side of the pawl in the direction of insertion, locking engagement is enhanced by the locking surface of at least one pawl tooth extending toward the apex of such tooth at an angle inclined toward the direction of insertion for locking engagement with a tooth of the first set of ratchet teeth; and by the locking surface of at least one of the first set of ratchet teeth extending toward the apex of such tooth at an angle inclined away from the direction of insertion for locking engagement with a pawl tooth.
