An irrigation pipe system including a tubular coupler member releasably connectable to fluid transport pipes. The tubular coupler member includes wing-like lateral projections for stabilizing and minimizing impact upon the tubular coupler member as it is drawn along a ground surface. Structure is provided for enabling a sprinkler riser to be connected to and disconnected from the tubular member by rotating the sprinkler riser less than about one rotation. A seal is also provided for preventing fluid leakage between the tubular coupler member and the sprinkler riser.
