Abstract: A lock for interior use for locking sliding windows and doors to prevent greater security and safety. The lock is provided with a pivotal blocker-arm that blocks movement of the sliding member of the window or door. A locking lever locks the blocker-arm in its locking state until released by a spring-biassed latching lever. A protective pivotal shield is provided that prevents access to the locking lever to prevent the unlocking thereof regardless of the position of the latching lever, and which allows access to the locking lever in a second state to allow unlocking of the locking lever but denying unlatching of the latching lever. The locking lever can only be unlocked if the latching lever is first unlatched followed by the positioning of the shield in its second state adjacent the latching lever.
