A door push bar lock-out retainer for a door having a swingable push bar. A member is swingably attachable to the door and can swing above the level of the push bar and then downwardly thereon and it has a hook for retaining the push bar in the unlocked position. A pin and an elongate slot form an attachment for the member so that it can swing above the push bar even when the push bar is in its unlocked position away from the door.
