## Abstract

For fastening to a carrier component, a blow-molded component has at least one integrally molded tab with an oblong recess. A detent hook on the carrier component is able to reach behind the tab when passed through the recess. The detent hook is more rigid than the tab, wherein the rigidity describes the resistance of a body to deformation by a force or a torque.

## Claims

### Claim 1

A fastening connection, comprising:
a blow-molded component having at least one integrally molded tab configured for the fastening connection, the tab having an oblong recess;
a carrier component having a detent hook, the detent hook being configured to extend behind the tab when passed through the recess, the detent hook being more rigid than the tab.

### Claim 2 (depends on 1)

The fastening connection according to claim 1, wherein the detent hook comprises a rigid material.

### Claim 3 (depends on 2)

The fastening connection according to claim 2, wherein:
the detent hook has an oblong basic body that projects away from the carrier component, and
a detent lug is located at an end of the basic body facing away from the carrier component, the detent lug being situated on at least one side of the basic body.

### Claim 4 (depends on 3)

The fastening connection according to claim 3, wherein the recess is narrower than the detent hook in an area of the detent lug.

### Claim 5 (depends on 2)

The fastening connection according to claim 2, wherein the recess is narrower than the detent hook in an area of the detent lug.

### Claim 6 (depends on 4)

The fastening connection according to claim 4, wherein edge areas of the tab surrounding the recess are elastically yieldable when the detent hook with the detent lug is pressed through the recess.

### Claim 7 (depends on 5)

The fastening connection according to claim 5, wherein edge areas of the tab surrounding the recess are elastically yieldable when the detent hook with the detent lug is pressed through the recess.

### Claim 8 (depends on 1)

The fastening connection according to claim 1, wherein
the tab comprises a nipple that projects from a longitudinal side of the recess into the recess in a center area when viewed in a longitudinal direction of the recess.

### Claim 9 (depends on 8)

The fastening connection according to claim 8, wherein the nipple is formed in one piece with the tab.

### Claim 10 (depends on 9)

The fastening connection according to claim 9, wherein the nipple is arranged on a side of the detent hook that faces away from the detent lug.

### Claim 11 (depends on 8)

The fastening connection according to claim 8, wherein the nipple is arranged on a side of the detent hook that faces away from the detent lug.

### Claim 12 (depends on 1)

The fastening connection according to claim 1, wherein an exterior edge area of the tab has a greater wall thickness than a central area of the tab in which the recess is located.

### Claim 13 (depends on 1)

The fastening connection according to claim 1, wherein the tab is located on the blow-molded component in an area corresponding to a parting plane of a blow-molding die that forms the blow-molded component.
