A flexible, sectioned plastic arm for a showerhead comprises a series of interconnected ball-and-socket (B&S) sections (10) with a proximal (shower pipe) end piece (12) and a distal (showerhead) end piece (14). Each B&S section has a proximal (cup or socket) end (10S) and a distal (ball) end (10B).

A flexible, sectioned plastic arm for a showerhead comprises a series of interconnected ball-and-socket (B&S) sections (10) with a proximal (shower pipe) end piece (12) and a distal (showerhead) end piece (14). Each B&S section has a proximal (cup or socket) end (10S) and a distal (ball) end (10B). The proximal end piece has a proximal end with female threads which can be screwed onto a shower pipe and a ball-shaped distal end for snapping into the socket of the most proximal section of the shower arm. The distal end piece has a proximal end with a socket for snapping onto the most distal end section of the shower arm and a distal end with male threads (12T) which can be screwed onto the showerhead. The arm has a through hole containing a series or chain of cylindrical brass or other metal sections, tubes, or sleeves (16). These prevent the arm from being bent too far, thereby to keep the B&S from separating. The two end tubes abut a pair of respective resilient spacers (18) or springs (18S), which in turn abut shoulders in the end pieces to keep the series of tubes in place. Inside the series of tubes is a flexible plastic tube (20) for carrying the water without leakage. A T-shaped end fitting (20T) is attached to each end of the plastic tube. These end fittings hold the tube in the arm. The top arm of the T of the distal end fitting sits in the bottom of the female threaded end of the proximal end piece. The top arm of the T of the distal end fitting sits on the very end of the male threaded end of the distal end piece.
