ABSTRACT:
A coupling device has a transversely arranged, open-end groove (30) in a flange attached to a pipe end. The groove in the flange receives a circumferentially arranged locking flange element (76) on the other coupling member and permits alignment of the bores of the coupling members when the locking flange element is in the open end groove. Upon alignment of the bores of the coupling members, a trigger member (60) is activiated to automatically release a spring biased tubular member (33) in one of the coupling members. The tubular member has a conical end (48) which is displaced into the other coupling member to lock the coupling members to one another. A tensioning nut (72) is threadedly movable on a coupling member so as to be moved into tightening engagement with the other coupling member.
