A closure device (14) for use with a movable closure member which is mounted for movement between open and closed positions with respect to a fixed frame in which is it mounted, and being intended to be mounted on a closing face of the closure member and to be co-operative with a keeper mounted on the fixed frame to lock the closure member in the closed position. The closure device comprises: an actuator device (15) which is adapted to be mounted in the closing face of the movable member; an elongate actuator element (16a) which is linearly displacable in a direction generally lengthwise of the closing face, and being displacable between an operative position and an inoperative position by operation of the actuator device; and at least one locking element (16) connected to the elongate actuator element (16a) and movable into and out of engagement with a locking formation on the keeper, and having an engaging portion which engages with the locking formation so as to resist forced separation of the closure device and the keeper in a direction generally perpendicular to the closing face. <IMAGE>
