A buckle has a main body, a strap retaining bar connected to the main body, two locking legs formed as separate pieces from the main body and pivotably connected to the main body; and a spring disposed between the two locking legs. The spring is attached to both of the locking legs, and exerts a force against the locking legs when they are pressed inward toward each other. The spring keeps the locking legs in an outwardly tensioned position, but does not let the legs flex outwardly in an unlimited manner, since the spring is directly connected to the legs. The spring allows the main body and locking legs to be formed of an inflexible material, such as metal. The locking legs are separate pieces from the main body and are connected to the main body via a pivot pin or other hinged mechanism.

An example buckle assembly includes a body and a latch. The body includes an integral whistle portion. The latch is configured to snapably mate with the body.

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.

A quick hook-up and release anchor belt assembly for adjustably interconnecting two detachably coupled belts that are especially suited in combination for constraining the abdominal portion of a weight lifter's torso, and the like, the belt being of substantial thickness. Each belt includes a flexible elongate length and optionally a rigid end portion. The belts are positionable and detachably attachable along their elongate length by means of hook and loop fasteners. A releasable toggle or connector is operable to instantly draw up or alternatively allow interconnected separation and attachment of the two end portions of the coupled belts.

A buckle includes a plug and a socket, the plug and the socket each being attached to a predetermined member and being capable of being connected to and disconnected from each other. The plug includes an attachment portion configured to be attached to the predetermined member and a pair of leg portions extending in the same direction from the attachment portion. An engagement portion is formed at each leg portion. Each leg portion is bent at a plurality of bending points between the attachment portion and the engagement portion in an extending direction of each leg portion. A U-shaped bridge is provided on inner side surfaces of the pair of leg portions, the inner side surfaces facing each other at vicinities of respective distal end portions of the pair of leg portions, the U-shaped bridge connecting vicinities of the respective distal end portions.

A monitoring device may be provided that couples to a wearable collar for an animal. A housing may include a cavity with an open top end and a cover movable between a first position wherein the cover closes the open top end of the cavity and a second position wherein the open top end of the cavity is exposed. An electronic device may be positioned within the cavity, the electronic device including a processor configured to receive or transmit information relating to the animal wearing the wearable collar. A first connection portion may be coupled to the housing and configured to attach to a first member of a first terminating end of the wearable collar. A second connection portion may be coupled to the housing and configured to attach to a second member of a second terminating end of the wearable collar.

A wearable animal information apparatus may be provided that includes a collar configured to be worn around a portion of an animal. The collar may include an inner surface that faces the portion of the animal during use and an outer surface that faces away from the portion of the animal during use. The animal information apparatus may include a base coupled to the collar and a housing configured to couple to the base via an attachment element. The housing may include a plurality of indicators providing visual information relating to at least one of a condition of the animal or an environment surrounding the animal. An electronic device, located within the housing, may include a processor configured to receive or transmit information relating to the animal. The base may include a cavity for receiving the housing and coupling the base to the housing via the attachment element.
