Abstract
A support plate has fluid-flow openings therethrough which openings are flared at their ends. Securing rings extend into the openings from opposite ends and have tapered lips firmly pressing the edges of membranes against the flared end surfaces of openings. The rings are fixed to each other to exert constant pressure on the membrane edges.
