Abstract: As assembly is provided for securing a door to a fixed object which allows the door to be locked from the outside with a conventional padlock, but which allows the door to be opened from the interior while the padlock is in place. The door has a first face, a second face and an edge. The fixed object typically includes an abutment. Means are provided for engaging the door to the abutment. The engaging means are disposed on the first face of the door proximate to the edge and are movable from an engaged position in which the door is engaged to the abutment, to a released position in which the door is disengaged from the abutment. Means are also provided for biasing the engaging means toward the engaging position. A flexible cord is attached to the engaging means. An active hasp is connected to the flexible cord distal to the engaging means and is disposed on the second face of the door.
