ABSTRACT:
A hub extends into the top of a pole and has a central web. A carriage bolt extends through this web with its nut exposed on the top of the web and its head below the web within the pole. The central support of the toggle rests on and engages the bolt head. This support has a base and two sides. The two sides of two arms are in juxtaposition to the support sides and are pivotally secured thereto by pins. The arms extend at an angle toward the hub and are in contact therewith to be cammed outwardly by the hub as the support is drawn toward the hub by the bolt thereby causing the distal ends of the arms to engage the pole. A spring on the support base resiliently forces the arms into contact with the hub and, prior to the bolt being drawn up, holds the arms sufficiently close together to freely slip within the end of the pole.
