Abstract
The ratchet buckle for tightening a strap under a ratchet action provides a lock to positively prevent the ratchet buckle from inadvertently releasing the strap. The lock requires a removable handle to be installed on the ratchet buckle before the lock can be released. The removable handle extends the ratchet buckle crank arm for increased leverage in exercising the ratchet buckle and when removed reduces the overall size of the ratchet buckle and eliminates a crank arm portion that would otherwise extend beyond the ratchet buckle base.
