## Abstract

A spacer device for spacing electrical harnesses in a turbomachine such as an airplane turboprop or turbojet is disclosed. The spacer device includes clips fastened on a support. A first clip is mounted on a harness via a retention device which prevents the spacer device from moving relative to the harness, and the spacer device includes a strip mounted around the first clip in order to close the first clip after a harness has been mounted in the first clip. The strip is fastened to the support in a non-releasable manner.

## Claims

### Claim 1

A spacer device for spacing electrical harnesses in a turbomachine, the device comprising:
clamping spring clips for clamping onto the harnesses, said clips being mounted spaced apart from one another on a common support,
wherein a first clip is mounted on a first harness via retention means for preventing any translation of the device with respect to the first harness, and
wherein the device includes a strip mounted around the first clip to close the first clip once the first harness has been mounted in the first clip, the strip being fastened in a non-releasable manner on said support.

### Claim 2 (depends on 1)

A device according to claim 1, wherein the strip comprises a U-shaped middle portion surrounding the first clip and two tabs formed at ends of the U-shape and fastened to the support by rivets or by spot-welds.

### Claim 3 (depends on 1)

A device according to claim 1, wherein the retention means comprise a sheath of plastics material surrounding the harness and having the first clip mounted thereon.

### Claim 4 (depends on 3)

A device according to claim 3, wherein the sheath is made of heat-shrink material.

### Claim 5 (depends on 1)

A device according to claim 1, wherein the support is a plane or bent strip of rectangular shape.

### Claim 6 (depends on 1)

A device according to claim 1, wherein the first clip is fastened to a middle portion of the support.

### Claim 7 (depends on 1)

A device according to claim 1, wherein the other clips are fastened to one of the support or the strip for closing the first clip.

### Claim 8 (depends on 1)

A turbomachine including a casing having electrical harnesses fastened thereon, wherein the harnesses are fitted with at least one spacer device according to claim 1.

### Claim 9 (depends on 8)

A turbomachine according to claim 8, wherein the spacer device is mounted on the harnesses between two points where the harnesses are fastened to the casing.

### Claim 10 (depends on 1)

A device according to claim 1, wherein the first clip is mounted on a first face of the support and the other clips are mounted on a second face of the support opposite the first face of the support.
