Abstract: An anti-locking device comprising a body with an inverted U-shaped channel wherein a T-shaped rod sits and can move laterally when rotated at certain configurations within the U-shaped channel, such that the T-shaped rod can move from an obstructing configuration and to an non-obstruction configuration, and vice versa. The anti-locking device is preferably attachable to a hinged door and the T-shaped rod is able to move laterally in the body of the anti-locking device. In an obstructing configuration, one end of the T-shaped rod would sit between a door and its corresponding doorframe to keep the door from closing, and in a non-obstructing configuration, the T-shaped rod would not sit between the door and the doorframe, allowing the door to close.
