A door security device is formed as a plurality of bars wherein a first bar is telescopingly received within a second bar. The extended length of the telescoping bars are of a span greater than that of an associated door frame. A bifurcated door knob latching bracket is orthogonally adjustable relative to the aligned axis of the aforenoted bars for positioning of the bracket in an overlying relationship to a door knob secured to a door fitted within the aforenoted framework. A pair of spaced resilient pad means are secured to each terminal end of the telescoping bars in contact with the door frame to accordingly prevent unauthorized opening of the door when the instant invention is secured relative thereto.
