A quick connect coupling for use in a high pressure fluid system includes a plug member in the form of a plug tube with an upset bead thereon that is adapted to be inserted into a socket member, a ring seal being positioned to encircle the pilot plug end of the tube. A split retainer is positioned to encircle the socket member and is provided with opposed sets of abutment surfaces at opposite ends thereof that are adapted to engage against the bead on the plug member and a flange provided on the socket member, respectively, when the plug member is fully inserted into the socket and a rigid locking collar is positioned to encircle the split retainer whereby to bias the split end thereof with its associate abutment surfaces radially inward into positive locking engagement with the flange of the socket member.
