A mechanical-magnetic locking device includes a first connecting component, a second connecting component and a magnet-armature structure. The first connecting component is provided with a locking element with a gap; the second connecting component is provided with a locking member matched with the locking element with the gap. A magnet is provided in one connecting component and an armature is provided in the other connecting component. The locking element with the gap is coupled with the magnet and the armature is coupled with the locking member. When opening the locking device, the magnet and the armature are relatively moved to each other, and the magnetic attracting area is substantially unchanged or increased, allowing the locking element with the gap and the locking member to move from the engaged position to the non-engaged position. The locking device has a self-locking function, locking with adjustable positions, smooth connection, good good haptic, not easy to open after connection and is stable and reliable.

A slipcover hook includes a first closed ring and a second open ring connected to the first closed ring. The second open ring has a slot located in spaced relation to the lateral sides of the hook. In one embodiment, the intermediate slot is located equidistantly from the lateral sides (i.e., in or proximate to the center). The first and second closed ring are coplanar. The central opening is configured to permit the passage of a loop of fabric through the gap or opening so that the loop can be introduced into or removed from the second opening.

A closure is shown and described, preferably for an orthosis, which has a belt assembly, having a first closure part (1) and a second closure part (21), which can be releasably connected to one another, wherein the first and the second closure parts (1, 21) have connecting means for belts of the belt assembly, wherein the first closure part (1) has a pin (3), wherein the second closure part (21) has a connection end (23) and a coupling end (25), and between the connection end (23) and the coupling end (25) a guide track (37) extending in a closure plane is provided, which extends from an entrance opening (41) to a guide track end (43), wherein the pin (3) has a first section (7) and a second section (9), wherein the dimensions of the first section (7) perpendicular to the direction of extension of the pin (3) correspond to the dimensions of the guide track (37) in the closure plane at the guide track end (43), and wherein the dimensions of the second section (9) perpendicular to the direction of extension of the pin (3) are greater than the dimensions of the guide track (37) at the guide track end (43), so that the second section (9) restricts a movement of the pin (3) relative to the second closure part (21) perpendicular to the closure plane.

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.

An attachment clip assembly (1) is provided that includes a clip configured to be coupled with a first component. The clip includes a hook (4) that partially encircles a slot (5). The assembly also includes an attachment member (2) configured to be coupled with a second component. The attachment member includes an elongated attachment bar (6) shaped to fit inside the slot defined by the hook of the clip. The clip and the attachment member are configured to couple the first component with the second component by rotating one or more of the clip or the attachment member in a first direction relative to the other of the clip or attachment member, inserting the attachment bar of the attachment member into the slot defined by the hook of the clip, and then rotating the one or more of the clip or the attachment member in an opposite, second direction.
