ABSTRACT:
For mounting a showerhead or the like to a pipe, a pivot ball is formed entirely of plastic material. It has a base internally threaded to attach to the pipe and a hollow shell coupled to the base so as to constitute the spherical portion of a ball joint. That spherical portion is composed of first and second mating approximately semi-hemispherical segments. The first segment is formed integrally with the base and the second segment is coupled to that base in establishment of the spherical ball. An internal tube extends from the second segment essentially through the entire assembly. In a second version, the internal tube is shorter but also serves to secure the two segments together. This version has a base which is externally threaded. Still another version has a different form of mating between the segments.
