Abstract: A closed sleeve support for cable marking has two or more consecutive and lengthwise opposed partial notches adapted to spread apart and accomodate cables having a wide diameter range, due to elastic opening of the notches.

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.

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.
