The French window (2) has two panes (3,4) one of which (3) is equipped with an espagnolette bolt (5). This bolt comprises an operating rod (9), which extends the length of the upright (8), engages at one of its ends (10) in a latch (11) located in a rabbet on the upper (12) or lower (13) cross member of the window frame (14). A strip (15) mounted in a rabbet of the upper or lower cross member of the first pane has two openings (21,22) able to receive the operating rod end. One of these openings (21) is located in line with the latch when the two leaves are closed, allowing passage and engagement of the rod end in the latch.
