ABSTRACT:
A locking device for securing a sliding window in either a fully closed or partially opened, vented position includes an elongated bar, a venting link and a clamp that attaches to the window channel. The bar may be attached to the clamp in either of two opposing orientations and thus may secure the window irrespective of whether the window opens to the left or the right. The bar is connected to the clamp by a retaining pin that engages a slot in the bar, and a spring-biased locking button on the clamp that engages one of two locking apertures in the bar.
