Improvement in a quick disconnect coupling that includes a tubular coupler half, having a radially outwardly-directed roller on an outer surface portion thereof; a tubular nipple half, having a push-to-connect mechanism, including a cup-shaped member, concentrically surrounding a nipple body portion, this mechanism including a locking device having a basically L-shaped contoured slot including a helically-directed ramp inlet and a locking slot portion; the improvement comprising that the push-to-connect mechanism includes the rotatable journaling of the cup-shaped member, for limited rotational pivoting relative to the nipple half; this mechanism also including a biasing member for concurrently normally biasing the cup-shaped member to an at-rest position relative to the nipple body. A method for joining includes an initial contact between the axially-aligned roller and the helical ramp; further interaction rotationally displacing the cup shaped member until the roller enters the locking portion, resulting in reverse pivoting of the cup-shaped member.
