<p>The window (2) has a lock (6) connected to flexible connectors (4) e.g. cords or cables, terminated by a safety spring (5). The connectors have movable bolts (3) guided inside a fixed frame (1). Grooves are formed on the respective bolts at determined position when the lock is in operating position, to unlock and release the window that is defective, for replacing the defective window with a new window. The connectors are controlled to lock a window assembly against the frame by the spring that assists a fastener for locking, through the bolts when the new window is repositioned on the frame.</p> |
