ABSTRACT:
A pipe system with a first and a second buttress, each buttress including a support tube having a central axis. The support tubes are axially aligned and spaced from one another. The buttress also includes a camming surface. A tubular first and second follower coaxially surround respective support tubes and are axially freely movable and rotatable thereon. The followers are proportioned and arranged to contact the camming surface so as to assume a respective first and second axial location as a function of a first and second rotational position. A pipe link comprises a rigid length of pipe having a length short enough to fit between the follower members when they are at their maximum spacing from one another, and long enough to be trapped by them when they are brought to their minimum spacing. The pipe link can thereby be inserted when the followers are turned so as to move apart from one another and can be trapped and held to form a fluid circuit when they are turned so as to approach one another.
