  • Patent number: 6712376
    Abstract: A quick release clamping mechanism for securing a sleeve about a tubular structure or post where the sleeve has first and second outwardly projecting lugs that may drawn together toward one another to compress the sleeve. Each of the lugs has a bore extending therethrough and is positioned on the sleeve such that the bores are generally aligned with one another. The bore on the first lug is internally threaded. The clamping mechanism comprises an elongate bolt member receivable through the bores in the lugs. The bolt member has a first threaded end that threadably engages the threaded bore through the first lug. The clamping mechanism further comprises a tensioning member operable between an engaged and a disengaged position. When in its engaged position the tensioning member bears against the second lug and draws the first lug toward the second lug to compress the sleeve. When in its disengaged position the tensioning member releases the force drawing the first lug toward the second lug.
