It should just pull apart. Make sure you're pulling it out and not down. If it's not coming apart, try using a hair dryer and blowing hot air into the head from underneath. The heat might loosen the plastic enough that it will slide apart easier. I. Know it can work for stuck joints so it might work for this as well.
