Abstract
A device is provided for the leaktight securing of semi-permeable membranes to opposite faces and around each orifice of a membrane support plate of a separatory apparatus which separates by selective permeability. Said device comprises two stamped metal rings which maintain sealing pressure on the membranes against the support plate and are attached to one another in a leaktight fashion by means of a sealing means situated between them. A separatory apparatus comprising support plates fitted with the above device is also provided.
