Abstract: The improved dredge floating pontoon pipe-line ball joint disclosed is adapted for releasably connecting adjacent ends of two conduit sections which are part of a dredge line. The improved ball joint includes: a ball member secured to an end of one of the conduit sections; a socket member secured to an end of the other conduit section and adapted to fit about at least a portion of the ball member; and a ring mounted on the ball member and moveable with respect to and on the ball member so as to permit relative, universal movement between the two conduit sections. A plurality of retention pins are carried by the ring at spaced intervals about the ring and are utilized to retain the ring on the ball member particularly during assembly and disassembly of the improved joint.A novel cooperating hook member and lug arrangement is utilized for locking the ring and socket member together, and for interconnecting the ends of the conduit sections.
