Abstract
Abstract A wind proof door knob tag especially for use with exterior doors includes integral flexible detent tabs between the opening through which the door knob passes and the opening which conforms to the outside diameter of door knob shaft. The tabs are cammed outwardly upon downward pull over the knob shaft and snap back into position to hold the tag firmly in place on the door knob despite wind conditions, thereby to prevent being blown away. The tab is made of a polyolefin sheet but could be made of a vinyl sheet which at the thickness utilized, prevents unauthorized opening of locks by insertion of this tag between a door and its associated jamb.
