Put some heat-shrink on the clips? –  Chris Johnson Feb 5 at 12:14

Wrap the teeth in heat-shrink tubing or electrical tape. It will still hold just as tightly, but without the teeth, the pressure on the wire being held will be less.

I like to tightly wrap rubber bands around the back of the clips to take some of the pressure off. That way, you can adjust the pressure to your liking. Sometimes I use the alligator clips to hold a pair of cheap soldering heat sink clips and use those to actually hold more delicate components.

See the heat sink clip in this picture: enter image description here
