    Abstract: An extricator handle includes a quick snap-on feature for easy attachment to jammed earth augers. The invention preferably comprises a pair of hand grip bars, a receptacle box, an adaptor element and a locking bolt. The shaft of the jammed earth auger is received in a cavity in the adaptor element. The earth auger includes a spring-loaded pushbutton which locks into a complementary aperture in the sidewall of the adaptor element. The adaptor element is received in a cavity in the receptacle box. A threaded aperture in the adaptor receives the locking bolt which passes through another aperture in the receptacle box.
