A rubber hose is coupled to a metal tube by a connector having an inner tubular component which is fixed within an internally threaded sleeve and which telescopes into the end portion of the hose. An externally threaded sleeve is rotatable on the end portion of the hose and, when tightened into the internally threaded sleeve, engages a nut on the end portion of the hose to force the tube axially onto a frustoconical portion of the tubular component and establish a seal around the hose. The thread of the nut is of opposite hand from the threads of the sleeves to prevent the nut from running off of the hose if the nut is turned during tightening of the externally threaded sleeve.
