ABSTRACT:
An assembly for coupling an implement to an operating arm of a machine generally consisting of a first component fixedly mountable on the implement, having an annular gripping surface, and a second component connectable to the operating arm having a pair of gripping members displaceable along a first line of travel into and out of gripping engagement with the gripping surface of the first component, and am actuator for selectively displacing the gripping members into and out of such gripping engagement, the first component having at least one pair of spaced abutment surfaces disposed in opposed relation to the gripping members for restricting displacement of the gripping members relative to the first component along a second line of travel intersecting the first line of travel and at least one abutment surface engageable by the gripping members for restricting displacement of the gripping members along the first line of travel for retaining at least a portion of the gripping members in opposed relation to the pair of abutment surfaces whereby the implement would be free to be displaced angularly relative to the second coupling component about the axis of the gripping surface and prevented from being fully separated relative to the second coupling component substantially along the second line of travel when the gripping members are out of gripping engagement with the gripping surface.
