Abstract: An annulated tubular sheath which is split down a longitudinal section thereof. According to the invention, a longitudinal strip of the sleeve is made of a flexible material and is disposed in an angular position of 5-180 degrees in relation to the longitudinal section or is disposed in the region of the sheath in which the longitudinal section is made. Preferably, the flexible material is a thermoplastic elastomer. The invention also relates to a method for producing a sleeve by extruding a plastic material, a longitudinal strip made of a flexible material obtained by co-extruding an elastomer material. A device for carrying out said method comprises an extrusion head provided with an insert for placing the co-extrusion in a stop position on a die in order to block the flow of the extruded plastic material and to enable the flow of elastomer material.

Abstract: The invention concerns a part for supporting and fixing an electric or electronic component, comprising a compartment supporting the electric component, two clamps each engaged and in electrical continuity with a pin of the electric or electronic component arranged in the compartment between the two clamps and a removable closure cap. The invention is characterised in that a blade is fixed on the closure cap to cut a electric wire engaged and in electrical continuity with the two clamps so as to mount the electric or electronic component in series on the electric wire. Preferably, the supporting and fixing part comprises a block to act as support for the electric wire when it is being cut by the blade and apertures providing clearance for the two strands of the cut electric wire.

Abstract: Installation device (4) for installing one or more longitudinally extending elements (2) on a panel. This device comprises a U-shaped retainer (1) to surround transversely the longitudinally extending elements (2), having flexible arms (20, 24) each provided with a series of notches (22,26). This device also comprise a base (30) having, corresponding to each arm, an inclined traversing passage (42) whose inlet opening (41) is located in the face opposite the retainer and show outlet opening (43) is located in the face opposite the retainer and whose outlet opening (43) is located in a lateral face of the base, each passage of the base (30) having a retaining hook (44) for the notch (22, 26) of the corresponding arm (20, 24) of the retainer, each flexible arm (20, 24) engaging in each corresponding inclined traversing passage (42) until the notches (22, 26) lock in the respective hooks (44) of the respective passages (42) to secure the longitudinally extending elements (2) to the base.

Abstract: The invention relates to a connecting box for fitting a tube to the aperture of a wall. This box includes at least two shells which are connected by a hinge at their common longitudinal joining face and are completed by locking means at their opposing longitudinal joining face, defining, once folded back and locked on one another, a rear part capable of receiving and retaining the end of the tube as well as a front sleeve including a thread designed to receive an integral nut behind the wall or to be screwed in the possible tapping in the aperture. The edges of the joining faces at least of the rear portion and the supporting surface delimiting the sleeve and this rear portion are equipped with a continuous strip or a layer of flexible sealing material.

Abstract: A grooved tubular protective sheath (10) with a slot and a longitudinal flange. In particular, the flange (24) is provided on one edge (16) of the slot substantially at the bottom of the grooves (12) and positionable under the other slot edge (17). The grooves are closed at the edges (16, 17) of the slot by transverse walls (22). A method for manufacturing a grooved sheath includes extruding and molding an annular sheath with a longitudinal flat strip level with flute edge hollows, cutting the flat strip along one of its flute edges to form a tongue that is integral only with the other flute edge. The method further includes heating the sheath and cooling it, while passing it between cones or calenders to bring the flute edges together, whereby the tongue passes between the cut edge. A device for making a grooved sheath includes a molding machine with two series of symmetrical parallel shells.

Abstract: A tubular sheath made from plastic material used for the mechanical and/or thermal protection of electric cabling is wrapped in a strip of sound-insulating material, the lateral parts of which have been inserted inside the sheath through the slit. The width of the strip, preferably produced from felt, is substantially equal to the sum of the external and internal perimeters of the plastic sheath.

Abstract: A connector for corrugated tubes comprises a lower shell (100) and an upper cover (150) having lateral walls (110, 160) with several corresponding semi-circular openings (50) that define, when the cover has been closed on the shell, circular openings for receiving corrugated tubes. The openings (50) are fitted with a series of flexible fingers (10) in the form of truncated segments of a circle that form flexible skirts in the form of a circular crown around the openings. Internal semi-circular ribs (40) for longitudinally locking the fitted corrugated tubes are situated on arcuate tongues (30) arranged in a plane parallel to the corresponding opening. Each tongue (30) is connected either to the inner wall by a flexible arm (29), or to the bottom of the shell by its lower middle part.
