Abstract: This invention is a locking means for a lever-controlled, swingable glass window, such as an automobile window wing. There is a locking lever for locking the window wing in a closed position. A base member is secured to the window support and in close proximity to the locking lever. A swing member has one end portion pivoted to the base member. One part of a female-male and boss-screw combination is carried by the swing member and the other part thereof by the base member. The swing member is thus adapted to swing on top of, and be locked to, the base member in its retracted position by said boss-screw combination or to be swung into an end to end alignment with the base member to its extended position. A hook member, which includes a U-shaped member having an opening, is pivotally connected to a mid portion of the swing member. The swing member may pass through the opening in the U-shaped member as the swing member turns between its said positions.
