A drain pipe obstruction clearing tool comprising an exterior cylinder having a plunger like head, a closed upper end with an aperture therein sliding and sealing engagement with a reciprocating handle shaft. The plunger face has a central aperture therein. Slidable through the central aperture of the plunger is a flexible hose-like piece that is normally retained within the outer cylinder in the stored condition. In the operative condition it extends its full length outwardly through the aperture in the plunger and is adapted to snake its way through the drain passage to the stoppage.
