Abstract
Abstract This open sleeve support is consisting of a central flat or slightly curved part (1), preferably of constant thickness, provided with two lateral branches (2) growing more narrow downwards, the latter being connected through a small fillet, to the two flat and parallel flanges (4) bent inwards and almost reaching the center of the sleeve, so that the support can be easily fitted on cables of various size (7) by slipping the sleeve on laterally, without risk of failure, while remaining firmly in place.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
160 words
Open sleeve support bearing marking elements for electric cables characterized by the fact that it is consisting of an upper central portion (1) either flat or slightly curved,.normally having constant thickness, two downwards estending legs or banches (2), connected to the central part (1), tapering towards their lower end, two flanges (4) connected to the end of the branches (2) by means of a close-bend fillet ( 3 ) having normally constant thickness, these flanges being parallel and extending upwards to almost the center of the sleeve, so that these sleeves can be slipped sideways on the cable, causing an only limited elastic deformation of the legs or branches (2) on the already connected cables (7) without any risk of failure, while the sleeves are kept in place by the elastic action of the flanges (4) and possibly of the branches (2), it being possible to use the same support on differently sized cables within a rather large diameter range.
Claim 2
Dependent Claim
160 words

Claim 3
Dependent Claim
34 words
Support as described in claim n O 1, characterized by the fact that the markings may be printed or stamped either separately or in groups on the upper surface of the central portion (1).
Claim 4
Dependent Claim
52 words
Support as described in claim n° 1 characterized by the fact that the marking elements, consisting of ring- shaped elements, to be composed in an identification code (6), introduced into one or more recesses.(5) these recesses to be in soft, transparent material, normally located in the central portion (1) of the sleeve.
Claim 5
Dependent Claim
21 words
Support as described in claim n° 1, characterizedby the fact, that the support is preferably in hard and elastic plastic material.
