Abstract: A reusable breakaway connector section for use with highway sign posts. An insert has a female receiver at its upper end. A plug having a lower male projection, is mated within the female receiver. A spring extends upwardly, from the upper end of the plug. A cable extends from the upper end of the spring, through the spring, the plug, and the insert, and is connected to the lower end of the insert. The cable compresses the spring, resiliently biasing the male projection into the female receiver while maintaining the insert, the plug, and the spring in axial alignment. The insert is installed in a ground sleeve and a sign post is installed over the spring and the plug. Lateral forces imposed on the sign post cause the male projection to be temporarily dislodged from the female receiver. Righting the post allows the projection and the receiver to mate again.
