There is no breakaway integrated, as this is the last resort kit. I dont want to loose it by a sily accident. Also it is too short to catch on somethig. However, in the case I need to get rid of it real fast (choking), I can a) tear the rubber frame from the tag and cut the string with the blade without even removing it; b) just pull on the tag in the right direction (from behind) real hard, it should go off the lock along with the rod and free wire's ends, which should let go one of the string's ends off under the tension.
