Abstract
A device for connecting two tubes end-to-end. At least one of the tubes is movable longitudinally to be connected to the other tube. A screwthreaded nut joins the two tubes. The first tube has at its end an outside screwthread of diameter d1 and pitch p1. The second tube has at its end an inside screwthread of diameter d2 greater than d1 and pitch p2 different than that p1 of the first tube. One of the screwthreads is continuous and the other is discontinuous by virtue of longitudinal lands subtending an angle at the center of the tube equal to that of the screwthreaded longitudinal lands. The nut 3 has an inside first screwthread compatible with that of the first tube and an outside second screwthread compatible with that of the second tube. The device further includes a system for immobilizing the tubes against rotation and a system for rotating the nut.
