Band-shaped device for forming a pipe-shaped protection cover

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.
