Abstract
Abstract The device comprises a sleeve which is helically preformed and deformable, a substantially central portion of the sleeve receives the splice which may optionally be reinforced by a channel section trough. The splice deforms the central portion which is secured in a housing provided in a support. The device is applicable to optical undersea cables.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
A device for positioning an optical fiber splice in a housing in a support, the transverse dimensions of the housing being greater than the radial dimension of the splice, wherein the device comprises a sleeve of a helically preformed and elastically deformable strip, the initial radial dimension of the helical strip sleeve being less than that of the splice, said splice being axially received in a substantially central portion of the sleeve and radially clamped in said housing by radial expansion of said central portion of said elastically deformable helical strip sleeve.
Claim 2
Independent Claim
92 words
A device for positioning an optical fiber splice in a housing in a support, the transverse dimensions of the housing being greater than the radial dimension of the splice, wherein the device comprises a sleeve of a helically preformed and elastically deformable strip, the initial radial dimension of the helical strip sleeve being less than that of the splice, said splice being axially received in a substantially central portion of the sleeve and radially clamped in said housing by radial expansion of said central portion of said elastically deformable helical strip sleeve.
Claim 3
Dependent Claim
43 words
A device according to claim 1, wherein said sleeve has an initial transverse dimension that is perceptibly less than the width of said housing and is directly secured therein by the radially deformed sleeve central portion jamming in the width of the housing.
Claim 4
Dependent Claim
28 words
A device according to claim 1, further including external means on said support for clamping said deformed central portion of the sleeve against a bottom of said housing.
Claim 5
Dependent Claim
17 words
A device according to claim 1, wherein said elastically deformable helical strip sleeve is made of plastic.
Claim 6
Dependent Claim
45 words
A device according to claim 1, further including means for reinforcing said splice, said reinforcing means being constituted by a channel section trough in which the splice is secured by a holding material within the trough, thereby together defining a reinforced splice in said sleeve.
Claim 7
Dependent Claim
13 words
A device according to claim 5, wherein said trough is made of steel.
