A locking device primarily for securing sliding members such as doors and windows in a closed position comprises at least one headed stud (12) provided on one member and a slidable locking plate (15) provided on the other member, said locking plate having a key-hole slot (18) which is releasably engageable with said stud (12), and a striker member (24) is associated with the slot (18) so as to prevent movement of the locking plate (15) from a releasing position to an operative locking position except when the striker member (24) is engaged by the stud (12). The striker member (24) thus prevents the locking plate (15) being moved to its operative locking position when the door or window is open, so as to ensure that the wider end (18a) of the key-hole slot is in register with the stud (12) when the door or window is closed. |
