ABSTRACT:
A showerhead or other water-dispensing assembly (100) is joined to a supply pipe (105) by a nut (110) and a collar (135). The supply pipe terminates in male threads (130). The nut includes a distal splined projecting section (120). The dispensing assembly includes a port (145) having a splined section (155), and an inner wall (160). The collar is slid onto the pipe, the nut is screwed onto the pipe, and the showerhead is held in its desired orientation while being urged toward the nut. As the distal splined projecting section enters the inner wall, the two splined sections engaged, preventing rotation of the showerhead on the pipe. The collar is then screwed onto the showerhead until it rests against the outer shoulder of the nut, thereby completing the non-rotatable installation.
