Description

ABSTRACT:
A security indicator has a two part telescopic locking bar attached to the handle of a door at one end and to the door or door jamb at the other end through an end piece. The device includes a cup or tube which encases the door handle, preventing use of the handle. The length of the bar is fixed by aligning apertures in each part of the telescopic locking bar to form a continuous aperture, inserting a frangible pin through the continuous aperture and locking the frangible pin in place with a padlock received by a hole in the frangible pin. The pin has a narrow portion which can be broken by relatively little human force. The device requires someone who does not have the key to the padlock on the frangible pin to break the frangible pin to enter a door fixed with the device. A broken pin alerts the occupant that an entry has occurred during his/her absence. A sleeve normally protects the narrow portion but slides easily away to expose the narrow portion when entry is desired.
