Abstract
Abstract A splice protection sleeve flange includes means for clamping a cable, a seal interposed between two rings, one of which can move along the cable, and a frustoconical threaded part which is screwed into the flange and acts both on the moveable ring and on the clamping means. In another aspect, a device for clamping a cable includes a ring on which fingers are each mounted in the form of a hinge, the free end of each finger terminating in a claw turned inwardly towards the axis YY′ of the ring and, on the side of the plane where the fingers do not lie, there is provided a means which, by shape complementarity, is intended to cooperate with another clamping device of the same shape but having a ring diameter greater or smaller than a value equal to the largest radial dimension of the fingers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
Splice protection sleeve comprising a flange defining a passage for a cable, the flange including means for clamping the cable, which means are intended to be positioned around the cable placed in the passage and to clamp it, and a seal interposed between two rings into which the cable is slipped and at least one of which can move along the cable and is displaced by means of a slide, wherein the slide is a frustoconical threaded part which is screwed into the flange by being slipped into the passage via its larger transverse surface and while being screwed in pushes the moveable ring towards the other ring and tightens the clamping means around the cable.
Claim 2
Dependent Claim
116 words
Splice protection sleeve comprising a flange defining a passage for a cable, the flange including means for clamping the cable, which means are intended to be positioned around the cable placed in the passage and to clamp it, and a seal interposed between two rings into which the cable is slipped and at least one of which can move along the cable and is displaced by means of a slide, wherein the slide is a frustoconical threaded part which is screwed into the flange by being slipped into the passage via its larger transverse surface and while being screwed in pushes the moveable ring towards the other ring and tightens the clamping means around the cable.
Claim 3
Dependent Claim
15 words
Sleeve according to claim 1 , wherein the other ring is immobilized in the flange.
Claim 4
Dependent Claim
20 words
Sleeve according to claim 1 , wherein the moveable ring is immobilized at the end of travel by a stop.
Claim 5
Dependent Claim
148 words
A splice protection sleeve flange defining a passage for a cable, the flange comprising: a clamp for clamping the cable relative to the flange, the clamp being positioned around the cable and within the passage; a pair of rings positioned around the cable and within the passage, at least one of the rings being movable along the cable; a seal interposed between the two rings and positioned around the cable; and a frustoconical slide configured to be inserted into the passage; wherein the slide displaces the moveable ring towards the other ring and tightens the clamp around the cable as the slide is inserted into the passage; and wherein the clamp comprises an annulus and a plurality of resilient bars extending from the annulus, each bar terminating in an inwardly facing claw that grips the cable when the slide is inserted into the passage and engages the clamp.
Claim 6
Dependent Claim
148 words
A splice protection sleeve flange defining a passage for a cable, the flange comprising: a clamp for clamping the cable relative to the flange, the clamp being positioned around the cable and within the passage; a pair of rings positioned around the cable and within the passage, at least one of the rings being movable along the cable; a seal interposed between the two rings and positioned around the cable; and a frustoconical slide configured to be inserted into the passage; wherein the slide displaces the moveable ring towards the other ring and tightens the clamp around the cable as the slide is inserted into the passage; and wherein the clamp comprises an annulus and a plurality of resilient bars extending from the annulus, each bar terminating in an inwardly facing claw that grips the cable when the slide is inserted into the passage and engages the clamp.
Claim 7
Dependent Claim
24 words
The flange according to claim 4 wherein the slide engages the moveable ring and the clamp when the slide is inserted into the passage.
Claim 8
Dependent Claim
138 words
A splice protection sleeve flange defining a passage for a cable, the flange comprising: a clamp for clamping the cable relative to the flange, the clamp being positioned around the cable and within the passage; a pair of rings positioned around the cable and within the passage, at least one of the rings being movable along the cable; a seal interposed between the two rings and positioned around the cable; and a frustoconical slide configured to be inserted into the passage; wherein the slide displaces the moveable ring towards the other ring and tightens the clamp around the cable as the slide is inserted into the passage; and wherein the other ring is immobilized in the flange and the moveable ring is immobilized by a stop positioned within the passage when the slide is inserted into the passage.
Claim 9
Dependent Claim
138 words
A splice protection sleeve flange defining a passage for a cable, the flange comprising: a clamp for clamping the cable relative to the flange, the clamp being positioned around the cable and within the passage; a pair of rings positioned around the cable and within the passage, at least one of the rings being movable along the cable; a seal interposed between the two rings and positioned around the cable; and a frustoconical slide configured to be inserted into the passage; wherein the slide displaces the moveable ring towards the other ring and tightens the clamp around the cable as the slide is inserted into the passage; and wherein the other ring is immobilized in the flange and the moveable ring is immobilized by a stop positioned within the passage when the slide is inserted into the passage.
