Abstract: A safety coupler for an air hose terminating in a plug. The plug has a passageway between its first and second ends for the passage of air there through. The coupler member has upstream and downstream ends and first body coupler passageway sized for receiving a first cylindrical section of the plug and terminating in a washer. A sleeve coupler and spring for biasing the sleeve coupler towards the coupler member upstream end, the sleeve coupler terminating at its coupler member upstream end by a bushing plug being sized to create a shoulder for abutting a raised stop of the plug. A reduced diameter plug receiving passageway is located downstream of the sleeve coupler and is sized to receive the plug and for receiving pressurized air passing through the plug passageway, and a sleeve slide valve threadably engageable to the washer such that when the plug enters the coupler member, the plug having a raised stop abuts the first body coupler resulting in the washer being displaced towards the coupler member downstream end whereupon the sleeve slide valve threadably captures the washer preventing the plug from disconnecting from the coupler member.
