At least one locating formation18stands proud of an operatively upper surface of each rail14. The assembly includes a plurality of screening modules12. Each screening module12has an end supported on the rail14so that a pair of modules12lie in end-to-end abutting relationship with the abutting ends, in use, overlying the rail12and defining a receiving formation through which the locating formation18protrudes to project beyond the receiving formation into a recessed region defined by the abutting ends of the pair of modules12. A locking member46is associated with the receiving formation and is receivable in the recessed region for engaging its associated locating formation to lock the pair of modules with respect to each other and with respect to the rail14.
