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 relates generally to first aid articles and more specifically tourniquets suitable for one handed application. One embodiment of the invention is directed to a tourniquet having a base defining first and second ends. A constricting band is attached to and extends from the first end of the base. A windlass handle is engaged with the constricting band. The constricting band is threaded through a self cinching stepped buckle. A buckle connector includes a hook member that engages the stepped buckle and is partly held in place through urging against a loop of the constriction band.

A harness including a waist belt to which two side attachment arrangements are connected; two forward attachment arrangements. A respective riser extends between each forward attachment arrangement and one corresponding side attachment arrangement. Each side attachment arrangement includes a securing component, typically in the form of a standing ring and a lying ring assembly. The securing component is connected to the waist belt, and the lying ring assembly is held by the securing component against the waist belt. The lying ring assembly includes a retention component that, in use, passes through a loop or an eye in the riser to connect the riser to the lying ring assembly. The retention component is removable from the lying ring assembly to release the connection between the riser and the lying ring assembly.
