I typically use a Park Tools Master Link Pliers (MLP 1.2) to remove and re-install. They don't need a lot of effort to unlock, but seems like enough that I've never worried (until now) that it might come undone while riding. They kind of "snap" back in pace on re-install.

I would worry if they didn't snap back in place or seemed really easy to unlock, but so far I've not encountered that. I've got 1500-2000 miles on one now that has been opened/closed at least a dozen times for cleaning.
