## Abstract

An article for forming a tubular protective cover around telephone and electrical cables comprising a generally flat band of material having opposite upper and lower surfaces and end edges, one of the surfaces being planar, the other surface being provided with a plurality of spaced grooves therein. Each groove is of V-shape and has inclined sides which intersect to form an apex proximate the planar surface to form a hinge where the band can be folded to enable the band to surround a cable. The other surface of the band is relatively flat between the grooves to define a continuous planar surface. At the grooves, the band is formed with elevations projecting beyond the plane of the surface in continuation of the sides of the grooves such that with the band folded at the hinges, the elevations at the sides of the grooves approach one another to provide a stiffening effect for the folded band around the cable. Snap-lock male and female elements are respectively provided on the band at the end edges for holding the folded around the cable.

## Claims

### Claim 1

An article for forming a tubular, protective cover around a cable, said article comprising a generally flat band of material having opposite upper and lower surfaces and end edges, one of said surfaces being planar, the other surface being provided with a plurality of spaced grooves extending parallel to said end edges, each groove having inclined sides which intersect to form an apex proximate said one planar surface to form a hinge thereat where said band can be folded to enable the band to surround a cable, said other surface of said band being relatively flat between said grooves to define a continuous planar surface, said band including elevations projecting beyond the plane of said other surface in continuation of said sides of said grooves on both sides of each groove such that with the band folded at the hinges, the elevations at the both sides of the respective grooves approach one another to provide a stiffening effect for the folded band around the cable, and locking means on said band on said band proximate said end edges for holding the folded band around the cable, said material of the band being a soft, extruded plastic, the configuration of said grooves and said elevations being such to enable said band to be wound into a roll.

### Claim 2 (depends on 1)

An article as claimed in claim 1 wherein said sides of said grooves form an angle at each groove such that said sides come into contact with one another when the locking means is engaged to hold the band around the cable.

### Claim 3 (depends on 1)

An article as claimed in claim 1 wherein said locking means comprises male and female snap-lock elements, said female snap-lock element being constituted as a groove provided in one of said end edges, said male snap-lock element comprising a projecting element on said other surface of a shape corresponding to said female groove for snap-lock engagement therewith, said projecting element being spaced from the other of said end edges such that with the male and female elements engaged, the portion of said band between said male element and said other end edge forms a grip position for opening and closing the cover.

### Claim 4 (depends on 1)

An article as claimed in claim 1 wherein said grooves are three in number and are arranged to form a square cross-section for the cover when the locking means is engaged.

### Claim 5 (depends on 4)

An article as claimed in claim 4 wherein the angle between the sides of the grooves is about 90.degree..

### Claim 6 (depends on 1)

An article as claimed in claim 1 wherein said elevations at said grooves are of V-shape.
