Abstract
A window locking system which prevents unintended opening of a window. The window locking system includes a base element which is attachable to a window and which forms a slot. Disposed within the slot is a latching member pivotally connected to the base element. The latching member includes a handle element and an oppositely disposed latching finger extending from opposite faces of the base element. A locking key which is rotatable between a locking position and an unlocking position is connected to the base element. The locking key prevents the latching member from pivoting from a closed position to an open position when oriented in its locking position.
