Don't Laugh - How to Detach JST connector?

I was trying this bl...y JST connector, because it is so small and convenient. Now I can't separate header and socket. They have latches and when they latch on, the only way to pray them open is with a blade.

Which of course distroys them completely. Is there un-destructive way to separate JST header and socket?

Does this help? removing JST connectors ?!? - SparkFun Electronics
