  • Patent number: 8544784
    Abstract: A line tightening device with a detachable handle, a hook and a coupler for securing the handle and the hook together while the tightener is being used. After the line tightener is used to achieve the desired tension in the line tightened, the handle and coupler can be quickly and easily disengaged and removed from the hook, thereby leaving only the hook attached to the tightened line. The hook is adapted for tightening the line by forming and fixing convolutions about its shank. A tether secures the hook to adjacent portions of the line to prevent accidental separation of the hook from the tensioned line.
