A lockable buckle for belts, straps and the like, consisting of an exterior housing, or shoe, accommodating a freely movable locking slide which forms, between it and the inside of the shoe, a locking area for nipping a belt or the like passing through the buckle. Locking is brought about by means of a manually operated eccenter mechanism engaging the rear end of the slide. The belt is arranged to enter the front of the buckle from below through an opening in the shoe and to pass over a rigid, profiled rib at the front end of the slide before entering the locking area under the slide. When the buckle is locked and the belt is under load, the tension in the belt will press this end of the slide against the belt, assisting the locking action exercised by the eccenter mechanism. One end of the belt can be secured to the rear end of the shoe by friction, by being threaded back and forth through openings in the shoe, and in such a way that it becomes strictly aligned with the other end of the belt, entering the front end of the buckle.
