Title: Flexible protective sleeve

Abstract: A sleeve having a longitudinally extending slit for covering wires or tubing is provided with a support layer of a continuous monofilament of formable metal wire or heat-settable monofilament formed into a multiplicity of spaced apart reversely bent crests and troughs. The continuous monofilament is bent to form a split tube having the crests and troughs in facing relationship. At least one outer layer is provided on said support layer. The outer layer may be an insulator such as a metal foil or metalized film, an abrasion-resistant material or a resilient sound-absorbing material. Inner layers may comprise insulating materials and/or felts, foams or other sound-absorbing materials. Various closure means for closing the longitudinal opening formed at the slit are disclosed.
