An interlock device is associated with two slidable assemblies (for example, the paper trays of a copier or the drawers of a filing cabinet) to prevent both assemblies from being moved to a withdrawn position at the same time. In the drawing, the slidable assemblies are indicated by the references 1,2 and are movable to the withdrawn position in the direction of the arrow (9), i.e., to the right as seen in the drawing. The interlock device comprises a cam (3) which is pivotally-mounted (at 4) and has opposed hook-shaped recesses (5,6) each of which is co-operable with a pin (7,8) on a respective one of the assemblies (1,2); in the neutral position shown in the drawing, each pin is located in the mouth of its respective recess.
