PURPOSE: A device to prevent a window from being separated from a window frame is provided to prevent a window from moving when the window is locked with the device as the window is opened a little. CONSTITUTION: One side of a separation preventing-plate(1) is bent up, and fixing holes(2) are formed in the bent up part. A guide groove(3) is formed in the other side of the separation preventing plate to guide and fix a stopper(5). A reinforcing projection(8) is projected from the upper and lower sides of the guide groove for the separation preventing plate. The stopper is inserted into the guide groove, and a screw rod(6) is projected from the center of the stopper. In the screw rod, a thread is formed. Fixing projections(4) are formed in the upper and lower parts of the rear side of the separation preventing plate. Fixing projections(4') corresponding to the projections of the separation preventing plate are formed in the upper and lower parts of the front side of the stopper. An adjusting knob(7) is fastened in the screw rod.
