An adjustable connector for elongated members is provided having a mount attached to a first elongated member, such as a chair support, and a tubular arm assembly pivotally connected to the mount and attached to a second elongated member, such as an umbrella or flag. The arm assembly is selectively positioned in relation to the mount by adjusting pegs that extend from the arm assembly and engage receivers in the mount. A tubular cam within the arm assembly is connected to a tubular sleeve on the exterior of the arm assembly. The sleeve is slid toward the mount causing the cam to disengage the pegs from the mount receivers permitting repositioning of the arm assembly from a position adjacent to the mount, through perpendicular to a position parallel to the mount. The connector may be collapsed and remain connected to the elongated members when not in use.
