<p>A lock or catch (10) is shown for a sliding door or window. The lock has a tongue (13) which can pivot to engage or disengage with a fixed frame part of a frame in which the door or window can slide. The lock has two buttons (16,17) which are respectively operable to move a lock (20,21,23,25,31) so the tongue (13) is moved to a first position (such as an unlocked condition) and to a second position (such as a locked condition). A cylinder lock (not shown) can be used to lock the lock and therefore the tongue (13) in a locked condition.</p> |
