A safety hose coupling and method are disclosed for a coupling assembly made up of a hollow male member and a hollow female member with a valve mounted therewithin and a lock actuation means movable first in one direction from a neutral position so that the male and female members can be assembled in a first locking position and locked in such position when the locking means is returned to neutral position. Then the locking means is moved in a direction opposite to the one direction and the male and female members moved further together to a second locking position and to open the valve whereby the locking means is then returned to neutral position to lock the male and female members together with the valve in open position.

A method of assembling a coupling assembly comprised of a male member and a female member including a normally closed valve and a locking member comprising the steps: moving said locking member in one direction from a neutral position, moving said male and female members together to a first locking position, returning said locking member to the neutral position thereby locking said male and female members together with said valve closed, moving said locking member from said neutral position in a direction opposite said one direction, moving said male and female members further together to a second locking position and to pen said valve and returning said locking member to the neutral position thereby locking said male and female members together with said valve open. In a safety hose coupler assembly including a hollow male member having an insertion surface on one end with an annular rib on the insertion surface, a hollow female member having a bore therethrough for receiving said male member insertion surface and having a valve mounted within said bore, which valve is movable to open position upon complete insertion of said male member insertion surface into said female member, and locking means for locking said male and female members together in fully coupled position with the seal open, the improvement comprising: at least a pair of locking means located on said female member for passing said annular rib therepast and for locking said annular rib in positions wherein said male and female members are either uncoupled with the valve closed or coupled against longitudinal movement with the valve closed or coupled against longitudinal movement with the valve open and locking actuation means movable in one direction from a neutral position in which both of said locking means are in locking position to a position wherein only one of said locking means is in locking position and movable from said neutral position in a direction opposite to said one direction wherein only the other of said locking means is in locking position.
