Abstract
This invention relates to an improved connector construction for releasably connecting one tubular member to another. A first tubular member has an aperture contained therein. A screw fastener member is mounted in the aperture. The screw fastener has an enlarged portion on the exterior of the tubular member preventing the screw fastener from passing through the aperture into the interior of the tube. The screw fastener member has a second enlarged portion within the tube. The space between the first and second enlarged portions is less than the thickness of the tube to hold the screw fastener member frictionally in the tubular member and to prevent rotation of the screw fastener member relative to the tubular member. A second tubular member has a portion positioned adjacent to the aperture in the first tubular member and the screw fastener member. A second screw fastener member is rotatably mounted in the second tubular member and is held therein. The second screw fastener member is threadedly mounted in the first mentioned screw fastener member connecting the second tubular member to the first tubular member.
