ABSTRACT:
A retaining device for connecting a tool head with a tapered eye to a tapered tongue of a tool handle. The retaining device includes two threaded, J-shaped bolts, a V-shaped plate having a hole in each leg for receiving the threaded portion of a J-bolt, and two hex nuts. The V-plate is positioned on the outer surface of the tongue with the J-bolts extending through the eye and latching a lower surface of the tool head. When the nuts are threaded onto the J-bolts and tightened, the J-bolts are drawn upwardly and radially outwardly, forcing the tool head into a secure, wedged engagement with the tool handle.
