ABSTRACT:
A quick connect/disconnect pipe coupling comprising a female receptacle member, a locking collar adapted to be slidably engaged over one end of the female receptacle member, and a male plug member adapted to be inserted into the collar engaged female receptacle member to form a tight connection therebetween. The collar includes radial locking flanges for engaging cooperating annular ridges on the plug and receptacle members, respectively. Slidable movement of the collar toward the receptacle member disengages the locking flange on the collar from the annular ridge on the male plug member thereby enabling a quick disconnect of the female receptacle member and collar from the male plug member.
