It's just a matter of drilling small holes close together on the orange piece and pulling it out with needle nose pliers. Or you can use a soldering iron to burn holes. you'll wan to crack up the orange peice and twist/pull it out of the hole
The alternative is to bake the housing in a 300 degree oven for 5 minutes and pry it open. Then you can simply take the piece out and then reseal the housing. Preferable a bit of extra black silicone to ensure a good reseal.
