I used two medium sized safety pins heatshrinked together so that the needle part is side by side. Push it in one side of the pin then the other side to flatten the tabs and pull to remove the pin. I meant to take a pic of the tool I used but forgot to. Oh and I didn't sleeve the 24pin. I bought a silverstone 20/24 pin extension and sleeved that instead. The Thermaltake PSU 24 pin was too short to get the nice loop I wanted.
