We use cable ties often   

Use one short thin cable tie and poke it through a hole to make a loop   

Use a super long cable tie and bend it at various points so it springs forward.   

Poke it in and wiggle it along until it arrives at the exit hole where you poke just the tip through the loop and pull it out to flick the tip out of the exit hole. Push further and it will start to come out. Easy.
