ABSTRACT:
A vertically elongated hollow rectangular box with vertical walls and an open top and bottom has a downwardly and rearwardly extending slot in one side wall. The forward edge of the slot bears a series of arcuate rearwardly facing notches cut into the housing. A removable bar rides in the slot, and bears a knob exterior the housing. When a flexible tube or hose is placed along the rear wall in the interior of the housing, the bar gradually contricts its diameter as the bar is moved downwardly in the slot. The notches keep the bar in place.
