ABSTRACT:
A locking device for air brake valves on vehicles is provided which comprises releasable elements for engaging an air brake valve control knob at the dashboard of the vehicle to prevent the control knob from being pushed inwardly to release the air brakes when the locking device is properly secured in place between the head of the control knob and the dashboard of the vehicle. A first element and a second element are adapted to be coupled together about the shaft of the control knob, and locked together. A portion for engaging the head of the control knob prevents removal of the head from the shaft of the control knob.
