A universal connector for interconnecting a pair of elongated elements in adjustable angular relation includes a pair of cooperative clamping members adapted to be clamped in place on one of said elongated elements and a third member adapted to be secured to the other of said pair of elongated elements. Each of said clamping members includes a clamping portion intermediate the ends adapted to clampingly engage a surface on one side of one elongated element and has first and second opposite end portions extending outwardly thereof. The first end portions of the clamping members are pivotally and releasably interconnected for permitting opposed intermediate clamping portions to move toward and away from each other between a clamping position and an open position. The clamping members also include a pivot for supporting the third member of connector to permit angular adjustment between the pair of elongated elements when the connector members are clamped and secured in place. A threaded fastener is provided for interconnecting the second end portions of the opposing clamping members to move the clamping portions thereof into clamping engagement against the elongated element to secure the universal connector in place for angularly interconnecting the pair of elongated elements.
