## Abstract

A housing for an electrical device comprises a housing bottom, a fastening element, and an unlocking element and is closeable by a housing cover. The housing bottom includes an elastically deformable connecting section to connect the housing to a machine, a technical system, or a building wall. The fastening element is disposed on an outer face of the connecting section and is connectable in a form-fitting and/or friction-fitting manner to a corresponding retaining element of the machine, the technical system, or the building wall. The unlocking element is disposed on an inner face of the connecting section and is operatively connected to the fastening element. The unlocking element is user actuatable only from an inside of the housing when the housing is open in order to release the form-fitting and/or friction-fitting connection of the fastening element to the retaining element of the machine, the technical system, or the building wall.

## Claims

### Claim 1

A housing for an electrical device, comprising:
a housing bottom including an elastically deformable connecting section to connect the housing to a machine, a technical system, or a building wall, wherein the housing is closeable by a housing cover;
at least one fastening element on an outer face of the connecting section, the fastening element being connectable in a form-fitting and/or friction-fitting manner to a corresponding retaining element of the machine, the technical system, or the building wall; and
an unlocking element on an inner face of the connecting section and operatively connected to the fastening element, the unlocking element being user actuatable only from an inside of the housing when the housing is open in order to release the form-fitting and/or friction-fitting connection of the fastening element to the retaining element of the machine, the technical system, or the building wall.

### Claim 2 (depends on 1)

The housing of claim 1, wherein the fastening element and the unlocking element are arranged opposite one another on the connecting section.

### Claim 3 (depends on 1)

The housing of claim 1, wherein the fastening element is integrally formed with the connecting section.

### Claim 4 (depends on 1)

The housing of claim 1, wherein the unlocking element is integrally formed with the connecting section.

### Claim 5 (depends on 1)

The housing of claim 1, wherein the unlocking element is configured to be grasped by a gripping tool.

### Claim 6 (depends on 1)

The housing of claim 1, wherein the fastening element is releasable from the retaining element of the machine, the technical system, or the building wall in response to exertion of a tensile force.

### Claim 7 (depends on 1)

The housing of claim 1, wherein the fastening element is releasable from the retaining element of the machine, the technical system or the building wall in response to exertion of a compressive force.

### Claim 8 (depends on 1)

The housing of claim 1, wherein the connecting section has a concentric, elastically deformable undulating structure extending around the fastening element and/or the unlocking element.

### Claim 9 (depends on 8)

The housing of claim 8, wherein the elastically deformable undulating structure comprises at least two ring-shaped ridges and at least one ring-shaped indentation between the ridges.

### Claim 10 (depends on 1)

The housing of claim 1, wherein the connecting section is integrally formed with the housing bottom.
