Abstract
Couplers for hand tools and extension handles are made up of two one piece fittings. Each fitting has an attachment element for connection to one of the tool and extension handle and a connecting element for joining the two fittings. Normally, one of the attachment elements will be a threaded male element and the other a threaded female element. The connector elements also are composed of a male and female element. The male connector element is a tube or rod with a dually tapered flange. The flange fits into a channel (depression) in the female connector element. The connecting elements are complementary in shape and size.
