Locking system for door on over-the-road vehicle

In combination:

• an over-the-road vehicle comprising a frame bounding a cargo space and at least one door that is movable between closed and open positions to selectively block and allow access to the cargo space,
• the at least one door comprising a first door with inside and outside surfaces, and a peripheral edge having a thickness dimension between the inside and outside surfaces;
• a first locking assembly connected to the over-the-road vehicle,
• the first locking assembly extending in an outside to inside/inside to outside direction over at least a portion of the thickness dimension of the peripheral edge and so that a first portion of the first locking assembly extends to beyond one of the inside and outside surfaces of the first door in one of an outside to inside/inside to outside direction;
• and
• a locking device having a cavity into which a part of the first portion of the first locking assembly can be directed,
• the first portion of the first locking assembly and the locking device configured so that with the part of the first portion of the first locking assembly directed into the cavity, and the first door in the closed position, the locking device can be changed from an unlocked state into a locked state wherein the locking device acts between the first locking assembly and another component on the vehicle, related to the first locking assembly, to maintain the first door in the closed position,
• wherein with:
• a) the first door in the closed position;
• b) the part of the first portion of the first locking assembly directed into the cavity;
• and c) the locking device in the locked state, a gap is maintained between the locking device and outside surface of the first door,
• wherein the part of the first portion of the locking assembly has an L-shaped portion with a base and a first transverse leg, the leg defining an upwardly facing surface,
• wherein the combination further includes at least one piece supported on the upwardly facing surface and projecting beyond the L-shaped portion and into the gap to thereby locally strengthen a region of the first portion of the first locking assembly so as to thereby resist severance or bending of the first portion of the first locking assembly exposed through the gap as might permit the first door to be moved from the closed position towards the open position to permit access to the cargo space.
