For preventing the spread, that is the radial widening, of the sides of a clip ring, a retainer or spread preventer is provided in the shape of a cup washer with the internal periphery of its annular ring part sized to engage the outer sides of the clip ring to prevent the clip ring sides from spreading. The clip ring may be disposed on a shaft, and the clip ring may be caused to spread wide by the shaft being moved axially, which draws the clip ring against a stationary abutment, and the retainer prevents such spreading.
