The buckles are flimsy cheap garbage.
I can't recall who, but it was brilliantly described that these things break doing what they were designed to do.
Actually if you want to get them to slide in and out with no problem, break off one of the latches on the male attachment. I had to do that with my Egon simply because the slit on the female attachment wasn't wide enough on one end to accommodate both latches, so I just broke one off and it holds just fine and as a result, slides out easily if you want it to.
Not that I recommend doing that because it's pretty bad in the first place I had to break part of it just to get it to attach. But only having it attached with one latch on the male end does enable you to detach the belt with ease if you wanted to.
