I just did this over the past weekend. I used a cheap pair of snap ring pliers from my FLAPs and ground them with a flat edge for grip. My CV boots had no clamps either so I just used a tie wrap around the end of the boot on the axle. The other end bolts to the CV to stay tight.
Good luck man!!!

PS My "spring washer" was facing away for the CV making it easy to get everything apart and back together. Was that incorrect???
