A method for installing a screen in a conduit includes the steps of draping the screen across a convoluted band of ductile material, positioning the screen-draped band within the conduit in general alignment with a continuous groove provided in the interior surface of the conduit, and expanding the convoluted band so that the band fits snugly in the groove to thereby hold the screen firmly in place with its periphery pinched between the band and the groove. The resultant screen retainer assembly has the advantages that the screen retaining means does not impede the flow of fluid through the conduit and that the expanded band cannot become displaced or accidentally removed.
