This cable 19 at distant points with respect to each other is suspended taut and thus with the rings C the lead A and the guard B under assembly will be held. The guard B will protect the lead A from weather elements and also from direct sun rays. By reason of the formation of the holder ring C there can be no rubbing or chaffing of the insulation of the lead and the guard-.willshield such insulation from attack of small sharp objects thrown or blown in the air or from limbs of trees or from squirrels and other animals that are liable to chew the "read; sheath.

In Figure 5 of the drawing the section 20 of the guard has connected therewith a terminal piece 21 for a lead-off for the lead A.

In Figures 6 and '7 of the drawing theis ection iguard, and. hook-like reversely disposed terminals on said legs for latching engagement with a suspension medium superposed with relation to said guard.
