Abstract: Method for manufacturing an assembly of two ringed sheaths (1,2) ready to be used to make a single ringed sheath around for example a bundle of electric cables (13), wherein two smooth-walled tubes are simultaneously extruded using a single extruder fitted with two extrusion nozzles, the two smooth-walled tubes are simultaneously molded into two ringed wall tubes using a molder equipped with molds each fitted with two ringed profiles extending in parallel in a longitudinal direction and being paired along one and the same parting line.

Abstract: Ringed tubular sheath comprising two open shells (33, 37), termed the outer (33) and inner (37) shells, both of the same diameter (D), one of which, the outer shell (33), has an opening (E1) smaller than the diameter (D) so as to engage by elastic deformation over the inner shell (37) in a closed position. In the course of this engagement, the opening (E1) of the outer shell (33) becomes stretched until it passes a point corresponding to the diameter (D) of the inner shell (37) and, beyond this point, returns to the unstretched position. In the invention, the two shells (33, 37) are connected to a hinge (17) so as to engage by pivoting about the hinge (17), the opening (E1) of the outer shell (33), which is smaller than the diameter (D), extending from the hinge (17) to an opposite edge (34) of the shell.
