- 1 - Abstract: A novel window security bar arrangement is described which is tamper-proof while also being easily openable by means of a lock in an emergency. It includes a plurality of tubular members telescopically associated to form a telescopic tubular assembly with a pair of outer ends. One of said assembly outer ends is connected to a hinge plate of a first hinge assembly including a pair of hinge plates, the other of said plates having holes for receiving screws to mount the plate to a first side of a window frame. A second hinge assembly includes a pair of hinge plates and one of this second pair includes a projecting bracket adapted for locking connection to the other of said telescopic tubular assembly outer ends, while the other of said second pair of hinge plates has holes for receiving screws to mount the plate to a second side of a window frame. The hinge assemblies are arranged such that when the bracket is connected to the telescopic tubular assembly, the screw holes in one hinge plate of each pair are covered by the other hinge plate of each pair so that the mounting screws cannot be removed.
