Abstract: The prevalent lockrods type rear-end closures for overland cargo carrying vehicles are exceedingly vulnerable to determined thievery. The high security locking assembly of the present invention is highly deterrent to thievery and comprises a hasp including a pair of J-shaped members respectively removably engaged with the two closure lockrods and having the apertured staple of the primary J-hook member cooperatively protruding through a slot of the secondary J-hook member. The two cooperating J-hook members are securely joinable with a padlock having its U-shaped bar passing through the protruding staple, and hence, protectively shrouded by the cooperating J-shaped members. When the lateral spacing of the lockrods is relatively close, the locking assembly prevents closure play as additional deterrent to thievery. The locking assembly will also accommodate relatively distant spacing of the lockrods and even if the two closure doors include a rearwardly protruding upright rib.
