Yeah, maybe it just came loose from opening the hood a lot or something. I don't think the clip is anything more than a stabilzer as the cable passes right through. Be careful with that big rubber plug. If you knock it out of place it is a SERIOUS PIA to get seated again. I ran my 4 guage cable through there for my stereo. I did it the lazy way (Jammed it through w/ a philips head) and tried to poke my wire through. As I was pulling the wire it pulled the whole plug out of place. Getting it back in was the hardest part of my install!
