Velcro or wide rubberbands (do a loop around a cable like you do on a velcro strap, then wrap the cable and add the loose end around the wrapped cable)
Just like any profession, the better care you take of your equipment the better it will take care of you. I dont keep any cables for which I don't have professional cable ties. A good company for a variety of durable plastic and velcro cable ties is Cabletiesplus.com.
