ABSTRACT:
A two-piece handle for use in positioning a vehicle lifting jack beneath a vehicle and for rotating a spindle of that jack, which handle comprises a jack handle rod, a jack handle rod extension, and a jack handle coupling for releasably interconnecting the jack handle rod and the jack handle rod extension in co-axial alignment. The jack handle coupling comprises a sleeve mounted over and fixedly secured to a knuckle joint of the jack handle rod and adapted to receive a knuckle joint of the jack handle rod extension. A spring wire engageable with the knuckle joint of the jack handle rod extension secures the two pieces of the rod in coupled engagement. Preferably, the knuckle joints of both sections of the jack handle are formed by bending the ends of the rods 180.degree. into a J-shaped configuration shaped to be permanently secured to the knuckle joint of one of the rods and to slidably receive the knuckle joint of the other rod.
