A fluid transfer hose coupling has a metal body with a tubular tail which has an exterior buttress thread. The shell of the coupling has an axial bore for screwing on to the tail and a threaded counterbore with an interior buttress thread of opposite hand. When the hose is inserted in the shell and the tail is screwed into the shell, the hose is squeezed and urged into the shell.
