Claim 1
Independent Claim
221 words
In combination: first and second tubular members having respective first and second end portions slidably engaged in telescopic relationship, the first end portion having an inwardly extending flange and the second end portion having an end disposed in axial alignment with the flange; said first end portion having in the wall thereof a series of spaced radially extending through holes; said second end portion having in the outer surface thereof a series of spaced openings, each opening being disposed in radial alignment with a respective one of said holes; a plurality of first fastening devices, each disposed within a respective one of said holes and said radially aligned opening; a plurality of cooperating second fastening devices, each being disposed within said second end portion, in radial alignment with a respective one of said openings and engaged by a respective first fastening; and means affixed to the internal surfaces of the second end portion for slidably supporting each of said second fastening devices at an oblique angle with the adjacent surface of said first end portion and including therebetween force converting means comprising respective wedge-shaped walls for converting radially directed forces exerted by said first fastening devices into bidirectional forces for moving the first and second end portions axially relative to one another while drawing the walls thereof radially toward one another.
