A pull ring for a buckle assembly that has a main body with a first hook element facing a rear end, and an actuation button. The actuation button is connected to the main body by a spring so that the actuation button can move between an extended resting position and a compressed position. The actuation button has a second hook element on a bottom surface and which faces the front end of the main body. The pull ring is connected to the main body and actuation button by fitting the pull ring around the first hook element, pressing the actuation button, pivoting the actuation button and main body until the second hook element is disposed within a central aperture of the pull ring, and releasing the actuation button so that the pull ring is retained in the hook elements under pressure by the spring.

A coupling device for releasably coupling two parts with one another includes first and second coupling members having magnets for holding the members with a magnetic holding force to self-center the members in an intermediate position. The coupling members are slidable to a locked condition in which mutual interlock portions engage and slidable to an unlocked position in which mutual unlock portions engage. The coupling members are uncoupled by sliding the members along a first unlocking path to the unlocked position and further moving the members along a directionally different separation path.

A clasp for a wristlet, the clasp including at least one set of four arms hinged with respect to each other so that the clasp can pass from a first position, referred to as the deployed position, wherein the arms are oriented radially towards the outside of the wristlet, to a second position, referred to as the closed position, wherein the arms are folded against each other so as to be placed under the wristlet, this set of four hinged arms including two sets of compasses formed by two arms joined by a hinge, the free end of the arms being mounted pivotally, on a first and on a second part of the wristlet.

A buckle assembly includes a first frame member defining a first slot, which includes a first open end positioned at a first side of the first frame member and which includes a first closed end positioned spaced apart from a second side of the first frame member; a second frame member defining a second slot, which includes a second open end positioned at a second side of the second frame member and a second closed end positioned spaced apart from a first side of the second frame member, wherein one of the first or second frame members has a pivot member upon which the first and second frame members are rotatable relative to one another; and a third frame member defining at least two slots which extend through the third frame member and is configured to position within a recess defined within the second frame member.

A closure device includes a first closure part which includes a base body and at least one closure element rotatably arranged on the base body about an axis of rotation. The at least one closure element includes a base body and at least one first locking portion arranged on the base body, and at least one second closure part which includes a base element and at least one second locking portion arranged on the base element. The first closure part and the at least one second closure part can be placed against each other along a placement direction.

Apparatus and associated methods relate to a pair of magnetic mating buckles including a first buckle (205) and second buckle (210), the first buckle extending beyond the second buckle's outer perimeter forming an extended lip. In an illustrative example, the lip may be manually manipulated to separate the first buckle from the second buckle when the pair of magnetic mating buckles are in a substantially planar magnetic engagement. In some examples, one or more magnets may be fixedly coupled to the first buckle, and/or the second buckle. In some examples, the buckles may be coupled to various webbings. In an engagement example, the first buckle may be inserted through a coupling aperture (215) in the second buckle. The coupling aperture may include one or more corner notches, for example. Various pairs of magnetic mating buckles with overhanging lips may advantageously provide leverage to manually separate the buckles without tools.

An anti-ligature restraint device is provided. The device includes a tub secured to a mounting location. A sealing element is inserted into the tub. The sealing element includes a restraint element slot to which a restraint is secured when the device is in an open position. The sealing element is disposed entirely with the tub in the closed position. A spring within the tub provides resistance to the sealing element as it is pushed into the tub and rotated to secure the sealing element within the tub. A lid lock secures the sealing element in the closed position. The device may be used in the concrete floor of a hospital room. In the open position, the device secures patient restraints. In the closed position, the device is flush with its mounting surface and locked, thereby preventing patient tampering or access to harmful elements thereof.

A safety harness comprises at least one strap, at least one attachment member for connecting the safety harness and a system for closing and adjusting the strap provided with a stationary fastening buckle secured to a first strand of the strap and a movable fastening buckle secured in such a way as to be adjustable along a second strand of the strap. The movable fastening buckle can cooperate with the stationary fastening buckle in an interlocking configuration in which the strap is closed on itself so as to form a closed loop having a perimeter that can be adjusted by adjusting the position occupied by the movable fastening buckle along the second stand. The safety harness comprises a locking part separate from the stationary and movable fastening buckles, secured to the first strand or the second strand of the strap and capable of varying between an active state urging the two, stationary and movable, fastening buckles relative to each other so as to positively immobilise the stationary and movable fastening buckles in the interlocking configuration, and an inactive state in which the two, stationary and movable, fastening buckles can freely adopt and come out of the interlocking configuration.
