Claim 9:
10. The device according to claim 1, wherein the operating rod is connected, by the devices for locking/unlocking, to the control handle to slide in coordination with the rotations of the control handle to obtain at least the limited opening configuration with the limited angle of the movable frame or leaf according to positions between:
a closed position of the movable frame or leaf corresponding to a first position of the control handle, wherein the operating rod is in a first position with the two protruding rod walls away from the two lateral openings of the slot of the guide body and the latch is in the second, raised operating position;
a rotation of the control handle to the limited opening configuration the limited angle of the movable frame or leaf, wherein the operating rod is in a second position in which the two protruding rod walls are in a closed position of the two lateral openings of the slot of the guide body and the latch is in the first, lowered non-operating position to allow the pin of the arm to slide along the slot to obtain the limited opening configuration of the movable frame or leaf with the limited angle;
a return rotation of the control handle to the closed position of the movable frame or leaf, wherein the operating rod returns to the first position with the two protruding rod walls away from the two lateral openings of the slot of the guide body and the latch is in the second, raised operating position to lock the pin of the arm in the position reached;

a further rotation of the control handle to the limited opening configuration with the limited angle of the movable frame or leaf, wherein the operating rod returns to the second position in which the two protruding rod walls close the two lateral openings of the slot of the guide body and the latch is in the first, lowered non-operating position to allow the pin of the arm to slide along the slot, in the opposite direction, to allow the movable frame or leaf to return to the closed position.
