Abstract
A series of successively sized segmented arcuate pipe couplings in which anti-mismatch members are provided to prevent the inadvertent connection of two different, but closely sized coupling segments together. The anti-mismatch features are provided on the ends of the arcuate coupling segments which (a) will nest when the proper coupling segments are brought together, but (b) will be in an interference non-nested relationship when a mismatch is attempted. This will prevent the fully bolt tightened connection of the size mismatched coupling segments, as well as a visual indication to a user that a size mismatch is being attempted.
