A portable chain lock for a chain binder used to tighten a chain holding a load on a truck flat bed. The portable chain lock has an open body with a pin fixed to a bottom wall and extending outwardly between a pair of sidewalls. One of the sidewalls has the first end of a locking chain fixed thereto while the other sidewall has a holding arm having an opening fixed thereto. The pin is passed through a chain link or other opening in one half of the chain binder when the chain binder is in the tightened position. The locking chain is wrapped around the other half of the chain binder with its second or free end looped over the holding arm and secured to the holding arm by a padlock passed through the opening in the holding arm, to thereby lock the chain binder in the chain tightened position.
