Abstract

A door security device can include a door member mounted to a swinging door, and a connector. The door member can include a slot having openings in at least one end and in an outer face. An end of a first leg of the connector can have a shape configured to mate with the first slot to permit the first leg to slide into the first slot such that the first leg extends out of the first slot through an opening in the outer face of the door member and such that a distal end of the second leg interferes with a surface of a door frame to prevent rotation of the swinging door relative to the door frame.
