cable ties should be alright as long as you have the rubber type gaitor. i had a plastic type one

and whenever i put the cabletie on it came off.
as for the metal clips, if its the one that im thinking it should be, you put it around the CV joint and do it up as tight as you can with the different settings on the clip, then use a pair of side cutters on the raised section of the clip and then crush it down to tighten.
i hope that helps
