Abstract
Abstract The invention relates to marking sleeves for electrical wires. It solves the problem of providing a sleeve which combines ease of manufacturing with possibility to use the sleeve on wires within a wide diameter range so that the sleeve is securely held in position also when carried by a thin wire. The sleeve is of the type made of a resilient synthetic resin and, according to the invention, its outer contour is substantially rectangular, whereas its inner contour, defining the passage, forms part-circular recesses for receiving wires within the lower portion of the diameter range.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
124 words
A device for marking electrical wires, cables and the like, comprising a body of a synthetic resin material having an inner passage for receiving the wire, the body being resiliently deformable so as to permit use thereof on wires within a given diameter range, characterized in that, in its undeformed state, the cross-section of the body, as seen in a plane perpendicular to the longitudinal axis of the passage, is such that its outer contour is substantially rectangular, whereas its inner contour forms inter-communicating part-circular recesses for receiving wires within the lower portion of said diameter range while retaining the substantially rectangular outer contour of the body, which is deformable to substantially annular form for receiving wires in the upper portion of said range.
Claim 2
Independent Claim
124 words
A device for marking electrical wires, cables and the like, comprising a body of a synthetic resin material having an inner passage for receiving the wire, the body being resiliently deformable so as to permit use thereof on wires within a given diameter range, characterized in that, in its undeformed state, the cross-section of the body, as seen in a plane perpendicular to the longitudinal axis of the passage, is such that its outer contour is substantially rectangular, whereas its inner contour forms inter-communicating part-circular recesses for receiving wires within the lower portion of said diameter range while retaining the substantially rectangular outer contour of the body, which is deformable to substantially annular form for receiving wires in the upper portion of said range.
Claim 3
Dependent Claim
15 words
The device of claim 1 which includes at least two part-circular recesses of different diamters.
Claim 4
Dependent Claim
15 words
The apparatus of claim 1 wherein each of said part-circular recesses extends more than 180°.
