Webs of profile securing the glass stack over surface of contact with glass have width equal to width of window frame both on the outer and inner sides of panel. Locking cord laid on outer side of fuselage is connected with frame of window by means of flexible loop which embraces locking cord and its branches embrace locking profile and frame of window passing through ear secured on frame in recess found on outer side of frame opposite to side of location cord removing ring. On side of lower base of stack frame is provided with cavity and drain passages communicating this cavity with chamber which is communicated in its turn with reservoir containing moisture absorbing agent by means of pipe line.
