Abstract
An assembly for axially coupling male and female tubes including a nut having internal threads on a polygonally shaped inner surface at one end that can be screwed onto a projection on one of the tubes so as to draw a collar at the other end of the nut into axial contact with a shoulder on the other end of said tubes so as to draw the tubes together, the said projection being such as to ride in said threads at points along the surface of at least one side of said polygon so as to bend it outwardly from its unstressed position.
