Abstract
Porous, tubular core sections coated with a semipermeable membrane are joined at their ends by a simplified coupling member. Each coupling member or connector comprises a cylindrical flange member having circularly barbed or serrated nipples which fit tightly into the ends of bores of adjacent core sections. The ends of the cores abut against the circular part of the coupling member. Surrounding the joint thus formed is a flexible, elastomeric sealing sleeve. The nipples on the coupling member are axially slotted and have neck parts of a smaller diameter adjacent the body part of the coupling member providing annular openings between these neck parts and the bores of core members permitting continuous flow of permeate and cleaning solution without there being appendages, cavities, or pockets in which permeate or cleaning solution could be trapped.
