A deadlock with a locking bolt having a tongue that is displaceable from a latched position to an unlatched position, the lock including locking means to displace the tongue past the latched position to a locked position. The locking tongue is similarly curved on both sides so that, in use, it slides past a striker plate to the latched position in both right and left hand locking doors. A multi-point deadlock in which a center lock is coupled to at least one auxiliary lock via transmission mesans. The center lock having handles coupled to the latching tongue of the center lock and the transmission means so that downward movement of either handle causes the center lock to unlatch and upward movement of either handle from the horizontal drives the transmission means to effect locking of the auxiliary lock. |
