ABSTRACT:
A security device to be usable with a dead bolt lock to prevent the lock from being opened from the outer side of an associated door. The security device includes a body member having a space for receiving a dead bolt lock handle and a slidable retainer for locking the handle to the body member with a pin. The pin is attached to one end of a flexible connector with the other end being affixed to an attachment plate mounted on the door. The flexible connector and attachment plate prevent the body member and handle from rotating due to unauthorized turning of the dead bolt.
