A reinforced locking mechanism for a casement window comprising at least one first eye hinge attached to any of a hanging stile, a shutting stile, a top rail and a bottom rail of the window sash, and at least one corresponding second eye hinge attached to a shutting jamb, a hanging jamb, an upper frame head and a lower frame sill of the window frame, respectively. Corresponding first and second eye hinges have coaxial eye portions and defining between them a longitudinal axis. A locking rod is displaceable along the longitudinal axis between a locked state in which it engages both the first and second eye hinges, and an unlocked state in which it is disengaged from at least one of the first and second eye hinges.
