<p>An elongated tubular member including inlet and outlet end sections is provided and each section includes inlet and outlet ends. The inlet end of the outlet section and the outlet end of the inlet section include coacting structure universally coupling those ends together for limited universal relative angular displacement about infinite axes extending substantially normal to the center axes thereof and for rotational angular displacement of the inlet section about its center axis relative to the outlet section while maintaining a good fluid seal between the universally connected ends of the sections. Hand-grip structure is carried by the inlet section and projects laterally outwardly therefrom. The universally connected ends of the sections are coupled together through the utilization of a hollow partial spherical bell terminal end on one of the ends and a hollow partial spherical bulbous terminal end on the other end universally received within the bell terminal end.</p> |
