A cover assembly for covering an elongate substrate includes a holdout device and a resilient, elastically radially expanded sleeve member. The holdout device includes a core having an axially extending slit defined therein and defining a core passage to receive the substrate, and a designated target region. The sleeve member defines an axially extending sleeve passage. The sleeve member is mounted on the core such that the core is disposed in the sleeve passage and the sleeve member exerts a radially compressive recovery force on the core. When the substrate is disposed in the core passage and a radially directed release force is applied to the target region, the core will reduce in circumference and collapse around the substrate under the recovery force of the sleeve member to a collapsed position.

The method for fitting a sheath on a cable harness includes a series of steps including determining the length of sheath to be used, mounting the sheath on a mounting tool of tubular shape, inserting the cable harness into the mounting tool, removing the mounting tool and arranging the sheath around the cable harness, fitting a sheath stop at one of the ends of the sheath, the sheath stop fastening the end of the sheath to the cable harness stretching the sheath over the cable harness so as to extend it and tension it, and fitting a sheath stop at the other one of the ends of the sheath.

A thermistor cable is formed from a tubing and a plurality of thermistor conductors bundled within the tubing, wherein each thermistor conductor forms a junction with a shared thermistor conductor to form a thermistor junction, and each thermistor junction is attached to a support cable in a thermistor bundle. The cable is formed by pulling the thermistor bundle into the tubing.

A flat wire including a flat conductor having at least one bent portion bent in an edgewise direction and a covering layer formed on the outer periphery of the flat conductor is provided, wherein the covering layer is formed by covering the flat conductor having bent portion with a heat-shrinkable tube and shrinking the heat-shrinkable tube.
