A flowmeter for measuring fluid flow including a body having a receptacle including a cavity formed by a threadless cylindrical side wall, a stopper adapted to be inserted into the cavity of the receptacle including a generally cylindrical threadless shank having an annular groove, and a clip member slidably located in a passage of the body. The clip member is slidable between a first position wherein the clip member is located within the annular groove of the stopper to prevent removal of the stopper from the body, and a second position wherein the clip member is located outside of the annular groove of the stopper whereby the stopper may be longitudinally removed from the receptacle of the body.
