Coyote hides tear pretty easily. I've torn 6 or 7 this season with just my hands....and I'm not a very big guy. 
I tried tarp clips, thinking they'd work...they just tore the hide, as well.
I remembered the golfball idea from when I was in highschool. A farmer would shuck deer hides off with his tractor using them. I'm not a golfer and didn't want to spend the money they want for new golf balls, so I opted for the plastic practice ones.
After skinning the back legs and tail out, I put the golfball inside the the hide (skin side), on each ham of the coyote. I grab the hide from the hair side with the golfball inside, then slip the noose over it. I wish I took a close up picture of it, but I didn't.
Here's the easiest way I can explain. Picture putting your fist inside a sock, then slipping a noose over it and onto your wrist. It makes for a good solid pulling area for the cord. The golf ball doesn't tear the hide, as it is round and not poking.
Hope this helps...Tony
