The problem is in the design. You need two hands to let go, you can't let go with one. The release mechanism requires you to push the handle in the other half before you can release it. This means that you can use one hand to release the locking mechanism and the other to take it apart. It's "easy" to let go, but if you have to use two hands here, don't do it fast enough.
