Abstract: A flexible protective sleeve (10; 20) for use in protecting an elongated member (W). The sleeve comprises a generally tubular wall (12; 22) for at least substantially surrounding the member. The sleeve also comprises resiliently-deformable projections (16; 24) projecting from an inner surface (18; 26) of the wall, the projections being arranged so that they cushion relative movement between the member and the wall.

Abstract: A tubular article of resilient material used as a protective sheathing for wires, hoses or other elongated substrates is provided with substantially circumferentially extending corrugations and a longitudinally slit side wall to allow for installation over the substrates. Fastening means in the form of hook-and-loop fastening tape is applied to the abutting edges of the slit so that the hooks and loops interlock when the slit is closed. The hook-and-loop tape protects the fingers of the worker during installation of the tubular article, prevents relative movement of the slit edges caused by turning and twisting forces, thereby eliminating undesirable noise during use and the need for taping following installation.

Abstract: Convoluted tubing for automotive wiring harnesses and other elongated substrates is provided with sound dampening qualities by filling the valleys between convolutions with a flexible, resilient foamed composition, such as silicone rubber, and foaming the composition to cause expansion of the foam so that ribs of foam project radially from the valleys. In a preferred embodiment, spaced apertures are formed in the valleys to allow the expanding foam to form radially inwardly projecting fingers which contact the wiring harness and act to dampen vibrations. The corrugated tubing may be axially slit and the slit allowed to be filled with the foamed composition which, when foamed, eliminates noises caused by movement of the edge surfaces of the slit when torsional forces are applied to opposite ends of the tube.
