Abstract
A dragline bucket rigging includes at least one pair of components removably secured together by a connector pin assembly including a U-shaped spring retainer clip. The clip removably snap-fits beneath a protective cap secured to the outside face of one of the components and within an open-ended channel defined between the cap and the component face. Legs of the retainer clip abut the sides of the channel and nest within a pair of diverging slots formed one on each side of a retainer pin when the latter telescoped through an opening formed within the cap and into a connector pin hole in the component. The legs thereby act to prevent the pin from rotating or being removed axially from the hole and yet the clip can be easily removed allowing the pin to be removed axially to disconnect the rigging components.
