Device for docking projection unit in aggregate at lateral wall of e.g. containment for treating sterile goods in chemical area, has bulge unit producing frictional closure for holding projection unit, during locking of attachment unit

摘要

The device has an attachment unit (2) arranged at a containment, and bordering a recess in a wall (11) of a containment (1). A clamping ring is provided for detachable connection of an aggregate (3) between the attachment unit and a projection unit. The attachment unit comprises an adjusting ring that is movable in an axial direction. The adjusting ring is fixed for implementing deforming effect on the clamping ring by creation of a bulge unit. The bulge unit produces a frictional closure for holding the projection unit, during locking of the attachment unit.
