## Abstract

A tubular component with an end section has a profile, wherein the profile comprises a plurality of holding elements axially offset in longitudinal direction of the end section. The holding elements comprise at least one first azimuthal contour region and at least one second azimuthal contour region, wherein the outer contour of a holding element in the first contour region at least in sections is lowered or raised relative to the second contour region and wherein the first contour regions of at least two holding elements are offset relative to each other in azimuthal direction.

## Claims

### Claim 1

A tubular component,
with an end section comprising a profile,
wherein the profile comprises a plurality of holding elements axially offset in longitudinal direction of the end section,
wherein the plurality of holding elements comprise at least one first azimuthal contour region and at least one second azimuthal contour region and
wherein an outer contour of one of the plurality of holding elements in the first azimuthal contour region at least in sections is lowered or raised relative to the second azimuthal contour region,
wherein the first azimuthal contour regions of at least two of the plurality of holding elements are offset relative to each other in azimuthal direction, and
wherein the plurality of holding elements comprise a substantially ring-shaped outer contour and the center axes of two neighboring holding elements are offset relative to each other.

### Claim 2 (depends on 1)

The tubular component according to claim 1, wherein the first azimuthal contour regions of two neighboring holding elements are offset relative to one another in azimuthal direction.

### Claim 3 (depends on 2)

The tubular component according to claim 2, wherein the first azimuthal contour regions of two neighboring holding elements are offset relative to one another in azimuthal direction by an angle between 15 and 180°.

### Claim 4 (depends on 1)

The tubular component according to claim 1, wherein first azimuthal contour regions of two neighboring holding each do not overlap in azimuthal direction.

### Claim 5 (depends on 1)

The tubular component according to claim 1, wherein first azimuthal contour regions of the plurality of holding elements are substantially distributed evenly over the entire azimuthal angular range.

### Claim 6 (depends on 1)

The tubular component according to claim 1, wherein first azimuthal contour regions comprise a flattening, a clearance and/or an elevation.

### Claim 7 (depends on 1)

The tubular component according to claim 1, wherein first azimuthal contour regions and/or second azimuthal contour regions are designed similarly or dissimilarly.

### Claim 8 (depends on 1)

The tubular component according to claim 1, wherein the center axes of two neighboring holding elements are offset radially relative to each other.

### Claim 9 (depends on 1)

The tubular component according to claim 1, wherein the outer contours of the plurality of holding elements are substantially designed similarly except for an azimuthal and/or radial offset.

### Claim 10 (depends on 1)

The tubular component according to claim 1, wherein the tubular component is designed of a plastic.
