A safety device, for use with pivot windows equipped with a child-safe device, has a hook 41 on a hardware part 4 which is shiftable on a hardware part 3 fixed to the sash frame and is adapted to cooperate with a hook 13 on one of the pivot arms 1 of the window, in order to lock the window against continued pivotal movement beyond a ventilation position. The safety device consists of a locking insert 5 which in its active position is situated between an upper end 42 of the shiftable hardware part 4 and a fixed abutment, for instance the sash frame end 21 of another of the pivot arms 2 of the window, said locking insert 5 having such a thickness that it does not prevent closing of the window in this active position. The locking insert 5 is concave on the end 51 adapted to cooperate with the fixed abutment. The locking insert 5 may comprise a magnet 53 adapted to cooperate with the fixed hardware part on the sash frame, in order to prevent free movement of the locking insert. |
