The button circumscribingly of a longitudinal axis of the shaft, defines a circumference slightly smaller than inside diameter of an outer end of the conduit such that the button has a base thereof mounted within the space having that inside diameter and is movable when pressed into space at the outer end of the conduit, there being a spring mounted to return the button and shaft to an outwardly biased state, and a retainer structure located at an inner distal end of the shaft retaining the shaft against unlimited movement outwardly in a direction along the shafts longitudinal axis. Intermediate of the axis is an O-ring seal movable with the shaft along the shaft's longitudinal axis within the space of the conduit.
