A locking system for a container-carrying trailer vehicle (10) having a loading platform (13) on which container (14) can be mounted, in which the locking system comprises a forward pair of locking devices (16) and a rearward pair of locking devices (17) mounted at forward and rear ends of the loading platform, and which co-operate with respective corner fittings (15) of the container (14) in order to clamp the container to the loading platform, in which each locking device (17) of the forward pair comprises: a housing (18), a bolt (20) mounted in the housing (18) to move linearly between an extended locking position and a withdrawn unlocking position; an actuator (21) coupled with the bolt (20) and operable to move the bolt to the unlocking position when the container is to be unloaded; a latch (24) mounted in the housing (18) to engage the bolt (20) and latch the bolt in the unlocking position; a torsion spring (22) biasing the bolt (20) to the locking position; a cam arrangement (26) mounted in the housing (18) and moveable between an actuatable position in which it projects from the housing (18) and into the loading space 50 as to be in the path of loading movement of the container (14), and an at least partly withdrawn position to which it is moved when engaged during the loading movement of the container; and an operative interconnection between the cam arrangement (26) and the latch (24) which can disengage the latch from the bolt (20) and allow the bolt to move under its biasing to the locking position when the cam arrangement is moved to its withdrawn position by the loading movement of the container.
