The invention relates to a quickly detachable self locking coupling which is simpler and cheaper to produce than other self locking couplings such as bayonet couplings and couplings using separate spring loaded ratchet devices or interference fits. The coupling comprises male and female screw threaded bodies, the thread on the male body having a step along its length, and the thread inside the female body consisting of only one turn of 360 degrees with flat ends. The parts are screwed together until the end of the thread in the female body rides over the step in the thread of the male body. A rubber ring then urges the threads together so that inadvertent unscrewing of the bodies is inhibited.
