ABSTRACT:
A releasable locking device for preventing premature coupling of a truck tractor's air braking glad hand to a truck trailer's air braking glad hand is disclosed. The device includes a set of jaws adapted to interlock with each other and the non air-connecting end of a glad hand. A channel integral with the set of jaws houses a barrel lock to effect control of the interlocking of the set of jaws with the non air-connecting end of the glad hand so that, when the set of jaws is interlocked with each other and the non air-connecting end of a glad hand, an operator may not prematurely couple a truck tractor's air brakes to a truck trailer's air brakes.
