Abstract
A self contained alarm device is disclosed for aiding in the prevention of the theft of articles from an automobile, such as a citizens band radio, by sounding an audible alarm in the event of an attempted theft. The device includes a box or container in which the article to be protected is mounted and at least one switch mounted on the outside of the container for articles, and at least one switch between the container for the articles and the lid for the container so that removing the container from the surface on which it is mounted will cause an audible alarm to be sounded. One embodiment of the device also includes an electrically conducting wire forming a loop outside of the container for encircling an element of the automobile such as the steering column so that if the loop is cut, the audible alarm will also be sounded.
