A portable auxiliary door lock includes a lock cylinder slidable upon a bar having toothed edges to engage the locking means within the cylinder. The device differs from such locks for sliding panels, as it provides for temporary attachment between the edge of an arcuately hinged door and the adjacent door jamb to secure the door when it is closed. One end of the bar is bent at a 90 degree angle to insert into the latch recess of the striker plate. However, rather than using the lock cylinder to abut against the door and thereby at least partially blocking access to the lock cylinder for actuation due to the adjacent door knob assembly, the cylinder faces away from the knob assembly and an additional stop plate is used to retain the door. Other improvements are provided, such as adjustment for the spacing between the door and the jamb and additional security to preclude the forced removal of the lock cylinder from the bar.
