A molded flexible fluid conduit and a make/before break pinch valve including a slidably movable pressure member spring biased normally against said conduit in closed condition of the valve, said conduit including a pair of elongate longitudinal unitary purchase formations capable of cooperating with slots carried by the valve whereby the conduit forcibly is pulled or stretched in diametrically opposed directions upon actuation of the valve subsequent to periods of closure so as to force the conduit open to permit flow.
