A window securing device ( ) for use in a double-hung sash window assembly having upper and lower sash window frames ( ) installed for relative overlapping vertical sliding movement, said upper sash frame ( ) having a recess into the interior of a vertical facial member of the window. The device ( ) includes a housing ( ) having a front faceplate opening ( ) into a cavity ( ) therein and a means for retaining the housing ( ) in the recess with the faceplate ( ) covering the edges of the recess. A pawl ( ) mounted in the cavity ( ) of the housing ( ) is spring biased into an extended position where the lowermost arresting edge protrudes through the opening ( ). In effect, the extended pawl ( ) blocks the pathway of a top portion of the lower sash ( ) for preventing further upward movement thereof. With the pawl ( ) in the extended position, the uppermost contact edge ( ) of said pawl ( ) is configured for abutting against an inside edge ( ) of the top of the opening ( ) in said faceplate ( ). A substantial portion of the upward force associated with the lifting of the lower sash ( ) against the arresting edge is transferred into the upper sash frame for enhanced resistance.
