Abstract: A tie device has a tie strap and a buckle for engaging serrations on a free end of the tie strap for retaining the free end of the tie strap in the buckle A passage extends through the buckle from an insertion end for receiving the free end of the tie strap to an exit end for exiting the free end of the tie strap. A cam action lock pawl is located in the passage for engaging the serrations on the free end of the tie strap to hold the free end of the tie strap in the buckle. The lock pawl has a first resilient leg that is attached to a fulcrum portion of the buckle; that slants upward with respect to a base wall of the passage toward the exit end of the passage and that terminates in a free end. The lock pawl has a second resilient leg that is attached to the first resilient leg and that extends back toward the insertion end of the passage.
