The people who designed this buckle got it "Half-Right" the part that secures the stationary end of the belt has the correct orientation to prevent slipping, but the part that is used to secure the end of the belt that you tighten is backwards (or upside down depending on your point of view). The "latch" part of the buckle will release the belt if you put much strain on it and cause the belt to come loose. They should have designed the hinge to be next to the front of the belt so that the securing toggle rotated against the belt tension pinning the belt between it and a plate riveted or welded to the back side of the buckle. This would have made the belt unable to come loose when tension is applied. This would be a great replacement buckle for web style belts if they hadn't goofed on the latch orientation. As it stands, you can count on the belt coming loose when you bend over or exceed a rather light tension.I suggest that the folks who make this, go back to the drawing board and "do it right".
