Abstract
A flexible tube-bending mandrel has a longitudinally-split shank link that is unthreaded, but recessed to receive a nut that threadedly engages the bolt for holding the link to a mandrel shank. The mandrel center links are longitudinally split for ease of assembly of their ball-and-socket interconnections and have their socket ends externally threaded to receive an internally-threaded ball segment that holds the center link sections in assembled condition and effectively restrains relative longitudinal motion of the two mating link sections.
