A locking bracket for securing virtually any commercial grade hand truck to the cargo bed of a delivery truck or any other surface for safety and security. The locking bracket generally comprises a flat mounting plate, a kick-lever pivotally attached to the mounting plate for kick-release, and a push rod attached to the other end of the lever. The push rod extends to a clamping mechanism including two upwardly protruding spaced blocks housing opposed laterally-closing clamping teeth. In operation, a hand truck is locked in place overtop in a standing position with the center strut of its nose plate clamped between the teeth. Urging the lever forward with one's foot drives the push rod which opens the clamping teeth for quick-kick release of the hand truck.
