The shield conductive path includes: a single-core conductor made up of a single conductor inserted into a pipe with a shield function, a stranded line conductor made up of a plurality of twisted individual wires connected to an end portion of the single core conductor, a sheathing that envelops the stranded line conductor in a state in which a junction portion of the stranded line conductor that is joined to the single-core conductor is exposed, and a shrink tube that envelops, protects and insulates the entirety of the single-core conductor and a portion of the stranded line conductor that is exposed from the sheathing.

A wire harness product clamping device includes a pair of cantilevers installed on a heat shrink machine and a plurality of wire harness fixtures that are different from one another and installed on the cantilevers to respectively clamp a plurality of wire harness products. The cantilevers are movable between a first position and a second position and rotatable between a use state and a storage state. The wire harness fixtures are outside the heat shrink machine to clamp the wire harness products when the cantilevers are in the use state and moved to the first position. A heat shrink tube on one of the wire harness products clamped by one of the wire harness fixtures is moved from outside of the heat shrink machine to inside of the heat shrink machine when the cantilevers are in the use state and moved from the first position to the second position.

A connection portion between a single-core line electrical line and a stranded electrical line is prevented from bulging in the diameter direction. A conductor exposed portion is formed on an end portion of the single-core line electrical line, and an individual wire exposed portion is formed on an end portion of the stranded electrical line. A collapsed portion is formed on the conductor exposed portion, and a connection block portion is formed by welding together individual wires of the individual wire exposed portion. The compressed portion and the connection block portion are joined in an overlapping state. At this time, the collapsed portion is bent such that a level difference is formed in the diameter direction such that the single-core line electrical line and the stranded electrical line are joined approximately coaxially.

A heat-shrinkable protective element having at least one protective layer is obtained from a polymeric composition having a polymer material, where the polymeric composition additionally has an electrically conducting filler having a BET specific surface of at least 100 m.sup.2/g according to Standard ASTM D 6556.
