Abstract: A device for the sealed closing of an opening for one or more elongate parts to pass through includes a sealing and/or clamping element with at least two interacting first and second parts that are axially displaceable relative to one another, and a pressure contour acting axially onto the sealing and/or clamping element. A first axial displacement of the pressure contour and an axial displacement of the at least one second part relative to the at least one first part causes a first change in geometry of the at least one first part transversely to the displacement direction. Also, a further axial displacement of the pressure contour causes a further change in geometry of the at least one first part transversely to the displacement direction such that the opening is sealed around the one or more elongate parts passing therethrough.

Abstract: A screw connection system can screw together at least one reinforced long molded part that includes at least one pressure element and a connecting part. The pressure element has a pressure contour. The connecting part has a clamping fixture. The clamping fixture includes a first inner clamping wall and a second outer clamping wall, between which a groove is formed. The pressure element can be applied to the connecting part, whereby the second outer clamping wall of the clamping fixture can be deformed by the pressure contour. The second clamping wall may be deformed radially inwards by the pressure contour. The second clamping wall may be deformable in the direction of the first clamping wall. The second clamping wall may be deformed such that it comes into contact with the first clamping wall when no reinforcement of a long molded part is arranged in the clamping fixture.
