Base and cover members 3, 8 are pivotally connected by a pin 13. The cover member can be rotated between an opened position and a closed position. A stopper member 9 with first and second claws is mounted on the pin to rotate around the pin. The cover member has an engagement wall 7. An end 15b of a belt 15 is inserted through the cover member, the cover member is rotated from the opened position to the closed position, and the belt is pulled in a direction of drawing the belt out of the belt buckle, and thereby, the belt is locked between the second claws and a bottom wall 5 of the cover member. At the same time, the rotational moment rotating the cover member toward the closed position is generated by the engagement wall of the cover member being pressed by the belt.

The disclosure provides a sling adjustment for increased reliability and performance compared to conventional cam and slide adjustments. The disclosed sling adjustment is a single hardware piece that includes a slider and a cam. The sling adjustment includes an antilock wedge to prevent or at least reduce binding when using the sliding feature in the tightening direction. Extruded pins are also disclosed that can reduce the cost and the number of components that are needed for reliable performance. In one example, the sling adjustment includes: (1) a slider having a pair of side walls, and (2) a cam, positioned within the pair of side walls, having an antilock wedge and a center slider bar, wherein the antilock wedge is located on a forward side of the center slider bar.

A belt buckle system includes a belt buckle frame member having an internal shaft, a first elongated actuator member slidingly positioned within the internal shaft, and a first latch member positioned within the buckle frame. The latch member rotates between an extended position and a retracted position and has a latch portion that extends outward from the belt buckle frame when the first latch member is in the member extended position and wherein the latch portion of the first latch member is positioned within the frame when the latch member is in the retracted position. The first elongated actuator actuates to transition the first latch member between the extended position and the retracted position.

The device for adjusting and clamping a strap comprises superposed first and second rings to define a slot for the strap to pass through. The second ring presses on the first ring. The slot for the strap to pass through is bounded by an outer edge of the second ring and an inner edge) of the first ring. The two rings are movable with respect to one another so that the slot for the strap to pass through is of variable thickness. A bottom surface of the first ring opposite the top surface of the first ring has a textured area provided with several salient elements designed to form an increased friction area between the strap and the bottom surface of the first ring. The textured area is separated from the outer edge of the second ring by the slot for the strap to pass through.

An adjustment system is configured to adjust the length of a first strap. The adjustment system comprises a ring defining a first through hole in a first direction. A pin is fitted movable with respect to the ring. The pin partially obstructs the ring in the first direction so as to divide the first through hole into a second through hole and a third through hole separated from the second through hole by the pin. The adjustment system comprises a tab at least partially blanking off the first through hole in the first direction. The tab is arranged at a distance from the pin to define a space for the first strap to pass between the pin and the tab.

The present invention is a buckle comprising: a lever having a first set of apertures and a second set of openings; a rod, wherein the rod is inserted through the first set of apertures; a pin, wherein the pin is inserted through the second set of openings; a base plate rotatably attached to the pin and positioned within the lever; a set of locking tabs in communication with the rod a bar rotatably attached to the pin; and a strap attached to the bar at a first end and releasably engaged with the base plate and the pin.
