ABSTRACT:
A quick detachable coupler having a tubular female member receiving a tubular male member. The end of the female member into which the male member is inserted consists of a stiff continuous ring of resilient material provided with a pair of diametrically disposed latches and with a pair of diametrically disposed pressure portions. The male member is formed with an external latching and locking ring having a lead surface which engages corresponding lead surfaces on the latches to spread the latches against the spring pressure of the resilient ring to allow the male ring to travel past said latches and to be locked in position within said female member by locking surfaces on the latches engaging corresponding locking surfaces on the male locking ring. To release the male member from the female member, the pressure portions are squeezed together to produce a slight flattening of the female ring which spreads the latches apart sufficiently to release said male locking ring.
