Abstract
A quick connect coupler for connection to a stud includes a female coupler body having a plurality of balls in ball receiving bores which are advanceable into a stud bore in the female coupler for engaging a stud upon advancement of the stud into the stud bore. The balls are held in engagement with the stud by a locking collar having an annular groove. The female coupler is disengaged from the stud by pressurized air acting against a plunger mounted within the stud bore and connected to the locking collar to drive the locking collar forward such that the annular groove is advanced into alignment with the ball receiving bores in the female coupler body. A blocking sleeve is mounted on a plunger shaft and biased forward to slide across the ball receiving bores as the stud is withdrawn to hold the balls out of the stud bore.
