A self securing theft proof chain binder, such as would be used to cinch a chain tightly holding a cargo to a truck flatbed. The binder has hooks on either of its ends to attach to the ends of the chain overlapping the cargo and the binder is pivoted in the middle so that when it has been squeezed together it tightly draws together the two ends of the chain. The lever arm on the binder has a projecting spur with a notched tooth thereon which in turn mates with a lock on the other half of the binder so that when the two halves are squeezed together they lock in place.
