ABSTRACT:
Each of a pair of housings is affixed to a corresponding side surface of a trailer and terminates at an open end at a forward surface of the trailer. Each of a pair of rigid elongated locking bars is retractably slidably mounted in a corresponding one of the housings and each is anchored at its first end in its housing. In retracted position, the locking bars are in the housings and extend to the forward surface of the trailer at their second ends. In extended position, the locking bars extend out of the housings for most of their lengths beyond the forward surface of the trailer to operative proximity with a rearward surface of the tractor in spaced parallel relation. Eyes are affixed to the rearward surface of the trailer. Each of a pair of padlocks releasably secures a corresponding one of the locking bars at its second end to an eye when the locking bars are in their extended positions thereby preventing the turning of the trailer relative to the tractor to prevent the turning of the tractor and trailer rig around corners and thereby discouraging theft of the rig.
