A tamper-resistant flow control attachment for shower installations is disclosed including a tubular housing adapted to be disposed between a shower arm and shower head. A first set screw locks the attachment to the shower arm. A tubular shell enclosing at least a portion of the housing and freely rotatable relative thereto conceals the first set screw. The shell includes a second set screw projecting into an annular groove in the housing for limiting axial movement of the shell. The set screws require a special installation/removal tool.
