ABSTRACT:
A self-locking cable guard for mechanically protecting an aerial cable from damage by squirrels and other animals comprises a longitudinally elongated body having an inverted-V cross section with the legs of the V bent inwardly toward each other to form bent leg sections so as to define a substantially enclosed cavity for receiving and locking onto the aerial cable. The bent leg sections are specifically configured and spaced apart by a predetermined distance to define an expandable resilient spaced gap which facilitates snap-on installation of the guard and at the same time prevents access to the enclosed cable by a squirrel's jaws.
