Abstract
Abstract This open support has the configuration of a "C" shaped sleeve (1) provided along the free ends of the "C" with two opposed lateral shapes (3) connected by weakened zones (2); each shape being provided with an inwards directed upper thin triangular projection (4) and a lower convex projection (5) so that during the assembly of the support (1) on the cable (6) the sleeve (1) is subjected to elastic strain and the shapes (3) begin to oscillate around the weakened zones (2) so that, due to an elastic thrust of the shapes (3) acting on the external lower semicircumference of the cable (6), the latter is pushed inwards and will snap into the sleeve (1) causing a further oscillation of the shapes (3) until they reach their end position while pushing the cable (6) inwards by boundary pressure.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
226 words
A support for identifying electric wire or cable, which comprises: (a) an elongated sleeve in the form of an open c having an internal central portion and opposed longitudinally extending free ends defining therebetween a longitudinally extending opening into said internal central portion, (b) at least one of said free ends of said sleeve being connected via a weakened zone to a longitudinally extending member operable to urge an electric wire or cable into said internal central portion of said sleeve, (c) said member having first and second portions projecting away from said weakened zone towards and away from said internal central portion of said sleeve, respectively, such that when said sleeve is mounted on a wire or cable by lateral pressure of the sleeve against the wire or cable, the sleeve will initially be subject to elastic deformation during its opening, while the member will oscillate around the weakened zone until it fits snugly around the wire or cable and, when the wire or cable is further pushed into the sleeve, elastic pressure of the member on the wire or cable will cause a snap action automatically pushing the cable into the sleeve and resulting in a renewed oscillation of the member around the weakened zone which will exert pressure on the wire or cable which rests inside the internal central portion of the sleeve.
Claim 2
Dependent Claim
226 words

Claim 3
Dependent Claim
22 words
The support according to claim 1, wherein only one of said free ends of said sleeve has a said member connected thereto.
Claim 4
Dependent Claim
28 words
The support according to claim 2, wherein the other of said free ends of said sleeve has a longitudinally extending crown-like swelling facing toward said internal central portion.
Claim 5
Dependent Claim
21 words
The support according to claim 2, wherein said first projecting portion is triangularly shaped and said second projecting portion is crown-shaped.
Claim 6
Dependent Claim
12 words
The support according to claim 2, wherein said member is concavely curved.
Claim 7
Dependent Claim
52 words
The support according to claim 5, wherein said first and second portions terminate in free ends, said second portion being sufficiently large such that said second portion free end will overlap said other free end of said sleeve when said wire or cable rests inside said internal central portion of said sleeve.
Claim 8
Dependent Claim
23 words
The support according to claim 5, wherein means is provided on said curved member to improve its grip on the wire or cable.
Claim 9
Dependent Claim
17 words
The support according to claim 1, wherein said sleeve has recess means for holding cable marking elements.
Claim 10
Dependent Claim
15 words
The support according to claim 8, wherein said recess means is holding ring-shaped marking elements.
Claim 11
Dependent Claim
17 words
The support according to claim 8, wherein said recess means has biasing means for holding flat labels.
Claim 12
Dependent Claim
26 words
The support according to claim 1, wherein both of said free ends of said sleeve has a said member connected thereto via a said weakened zone.
Claim 13
Dependent Claim
29 words
The support according to claim 11, wherein said first projecting portion of each said member is triangularly shaped and said second projecting portion of each said member is crown-shaped.
Claim 14
Dependent Claim
16 words
The support according to claim 12, wherein said first projections of said members are almost touching.
