## 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.

## Claims

### Claim 1

A device for the sealed closing of an opening for one or more elongate parts to pass through, the device comprising:
a sealing and/or clamping element consisting of at least two interacting first and second parts which are axially displaceable relative to one another; and
a pressure contour acting axially onto the sealing and/or clamping element, wherein 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, and wherein a further axial displacement of the pressure contour causes a further change in geometry of the at least one first part of the sealing and/or clamping element transversely to the displacement direction.

### Claim 2 (depends on 1)

The device according to claim 1 further comprising:
a cylindrical reception with an opening region for inserting at a wall or in a wall or at a stud being attachable to a wall or formed in one piece with it, into which the sealing and/or clamping element having a through hole is inserted; and
a pressure screw, a cap nut or a pressure part with the pressure contour, which can be put into, put onto, or screwed into or onto the opening region of the cylindrical reception and which acts upon the sealing and/or clamping element.

### Claim 3 (depends on 2)

The device according to claim 2, wherein the sealing and/or clamping element consists of at least two, tube-like, first and second parts, the first part or second part being connected with a first end region to a delimiting contour of the cylindrical reception as an axial path limitation when the second part is plugged onto the first part and engaging over the first part at least partly in an axially displaceable manner.

### Claim 4 (depends on 3)

The device according to claim 3, wherein a second end region of the first part and/or of the second part is radially deformed through a thickening of the second part and/or the first part when the second part is at least partly or completely slid onto the first part.

### Claim 5 (depends on 4)

The device according to claim 4, wherein the pressure screw, the cap nut or the pressure part comprise the pressure contour that radially deforms the first tube-like part and/or the second tube-like part when the first part is axially displaceable relative to the second part into a nominal assembly position.

### Claim 6 (depends on 4)

The device according to claim 4, wherein the thickening is a thickening arranged in the second end region of the second part that radially decreases the geometry of the through hole, wherein the second end region of the first part is, through the thickening when the second part is at least partly or completely slid onto the first part, deformed radially inwards, and that in the pressure screw, the cap nut or the pressure part with the pressure contour is formed by narrowing its clear width, by means of which at least the second end region of the second part is together with the first part in a nominal assembly position deformed radially inwards.

### Claim 7 (depends on 1)

The device according to claim 1, wherein the first part or the second part has an essentially constant thickness over its length.

### Claim 8 (depends on 1)

The device according to claim 1, wherein the first part and the second part have approximately a same length.

### Claim 9 (depends on 3)

The device according to claim 3, wherein the first part and the second part in a first assembly position abut at their end faces to the delimiting contour.

### Claim 10 (depends on 6)

The device according to claim 6, wherein the decreasing thickening is arranged in the second end region of the first part and/or in the second end region of the second part, and the first end region facing the second region is thin-walled.

### Claim 11 (depends on 6)

The device according to claim 6, wherein the decreasing thickening in the first assembly position and in the nominal assembly position forms a tapering of the through hole.

### Claim 12 (depends on 1)

The device according claim 1, wherein the first part and the second part have at least one area overlapping each other with sliding surfaces facing each other.

### Claim 13 (depends on 1)

The device according claim 1, wherein the second part has a sliding surface facing the pressure contour.

### Claim 14 (depends on 1)

The device according to claim 1, wherein the pressure contour is formed by an inner wall tapering conically, spherically, or convexly in the direction of the opening.

### Claim 15 (depends on 2)

The device according to claim 2, wherein a circumferential protrusion is arranged in the pressure screw, the cap nut or the pressure part, which supports one or more tube-like parts in an axial direction.

### Claim 16 (depends on 1)

The device according to claim 1, wherein at least one of the first part and the second part have circumferential axially and/or obliquely directed channels, grooves, slots or similar material tapering and/or material recesses.

### Claim 17 (depends on 1)

The device according to claim 1, wherein the first part and the second part are made of a plastic.

### Claim 18 (depends on 1)

The device according to claim 1 further comprising a support contour in the form of an axially protruding support collar, wherein the first part comprises a first end region supported inside radially circumferentially by the support contour and a second end region aligned inside radially circumferentially with the support collar to form a stepless mantle inner surface through which an elongate part can be passed through.

### Claim 19 (depends on 1)

The device according to claim 1, wherein the second part is made of a dimensionally stable plastic.

### Claim 20 (depends on 19)

The device according to claim 19, wherein and the first part is made of an elastomer, a rubber-elastic plastic that conforms to the dimensionally stable plastic of the second part.
