Assembly having a self-clamping skirt for closing an annular collar or connecting to same, which can be rapidly positioned and removed, and used in the biopharmaceutical field

Abstract

A mounting assembly is provided including a first piece mounted in a fixed, detachable, and sealed manner, on a rigid, annular collar of a second piece having an end opening. The first piece includes an annular peripheral wall having an inner face configured to contact an outer face of the collar. The first piece includes a transverse wall that can enter the opening, and an annular wall forming a skirt, the inner face of the skirt including a larger diameter part, a smaller diameter part, and an intermediate part configured to contact with conjugated parts of the outer face by clamping. The transverse wall and the skirt form one component and are made of a highly flexible material enabling the first piece to be brought into an intermediate state in which the first piece is enlarged to be removed from the second piece, while retaining elastic deformation.
