A double-shank ball fitting has a ball with integrally formed shanks projecting in opposite radial directions from a center of the ball for releasable locking engagement with a mating fitting having a pair of longitudinally aligned, reversed keyhole openings sharing a common ball swivel cavity with individual grooves disposed along opposed major surfaces of that mating fitting to form longitudinally aligned, shank-receiving slots.
