Abstract
A joint for demountably clamping a tubular member into a main bore in a socket comprises an auxiliary bore directed perpendicular to the axis of the main bore and intersecting it over a small arc and first and second collets that fit in the auxiliary bore. Part cylindrical bearing faces on the collets are shaped to conform to the curvature of the tubular member. A clamping bolt urges the collets together so that they press on the tubular member and retain it in the socket. Preferably a reinforcing insert fits the end of the tubular member and has a disc or annulus that registers with the collets to resist compressive loads on the tube.
