ABSTRACT:
An end play take up retaining ring between a support element and a retained element is constituted by a longitudinally split sleeve defining at a first end thereof a closed-biased C-shaped spring and at a second end thereof a larger open-biased C-shaped spring. The closed-biased C-shaped spring is expanded to fit the retaining ring over an external annular groove in the support element. At the same time, the open-biased C-shaped spring is squeezed to a smaller diameter. When the closed-biased C-shaped spring is released, it resiliently clamps the retaining ring in the annular groove. When the open-biased C-shaped spring is released, it resiliently expands and thrusts a beveled shoulder against the retained element. The beveled shoulder converts expansion of the open-biased C-shaped spring into relative lateral thrust which seats the first end of the retaining ring against an end wall of the annular groove and the retained element against a stop on the support element. Thrust by the retained element on the retaining ring closes the open-biased C-shaped spring to collapse the retaining ring to a cylinder which radially overlaps the annular groove to prevent dislodgment of the retained element from the support element and vice versa.
