ABSTRACT:
The present invention is an attachment device and a method for fastening and removing an electrical cable monitoring instrument to an electrical cable. The attachment device comprises monitoring instrument sensor with opening for positioning electrical cable such that said electrical cable can be positioned to pass through the sensitive volume at least partially surrounded by said sensor, at least one elongated elastic member securely attached to said cable monitoring instrument such that, when elastically deformed to a shape characterized by high mechanical energy such that deformed elastic member allows said electrical cable access to and from the sensitive volume at least partially surrounded by said monitoring instruments sensor. The elongated elastic member, when relaxed to the a shape characterized by lower mechanical energy than high mechanical energy shape, with the electrical cable positioned to pass through sensitive volume, applies elastic force to the electrical cable to hold the electrical cable passing through the sensitive volume firmly and securely in contact with the cable monitoring instrument with no relative motion.
