A sash lock to provide a locking effect to prevent relative sliding movement between first and second elements. The sash lock includes a mounting (11) for mounting with the first element. A keep (14) is provided for mounting with the second element. A first cam member (12) is coupled with the mounting (11) and movable from a non-locking position to a locking position where the cam member interengages with the keep (14). A second cam member (15) is coupled with the mounting (11) and movable with the first cam member (12) from a non-locking position to a locking position where the second cam member (15) also interengages with the keep (14). The first and second cams (12, 14) in use, and when in the locking positions, prevent relative sliding movement between the first and second elements. |
