A system for attachment to webbing has an attachment portion and an operating portion that can be attached to and detached from each other. The attachment portion has a base body with a cavity, a transverse bar, and two locking hooks. The operating portion has two side legs, top sections connected to the side legs, a gap between the top sections and a locking hook on each of the top sections. The operating portion is connectable to the attachment portion by pressing the legs together and inserting the locking hooks of the operating portion into the base body, and then releasing the legs so that the locking hooks of the attachment portion and operating portion engage each other. The operating portion is detachable from the attachment portion by squeezing the legs together until the locking hooks on the operating portion clear the locking hooks on the attachment portion.

A buckle includes a tab having a first side opposed to a second side and a receiver having a first side opposed to a second side. A first pair of pawls is pivotally connected to the first side of the tab. A cavity is defined in the receiver between the first and second sides of the receiver and configured to receive the first and second sides of the tab. The first pair of pawls has a locked position in which the first pair of pawls is engaged with the receiver to prevent movement of the tab with respect to the receiver and a released position in which the first pair of pawls permits movement of the tab with respect to the receiver. A first button on the first side of the receiver has a released position that moves the first pair of pawls to the released position.

A fastener having two strap ends connected by an elastomeric member is described. The elastomeric member has sufficient elasticity to allow a user to increase the distance of separation between the two strap ends by applying a tension force, while providing enough tension to return the two strap ends to close proximity when the user releases the tension force. The elastomeric member may also have an adjustable elasticity to accommodate different applications with different load forces.

An inserting buckle comprises an insertion piece, a buckle body, an ejection member, a first pressing buckle and a second pressing buckle. The second pressing buckle movably disposed in the cavity and moved toward or away from the first pressing buckle; the second pressing buckle is driven back by a second elastic member; a buckle hole is formed between the first pressing buckle and the second pressing buckle; the connection portion is inserted into the cavity and is locked in the buckle hole; the first pressing buckle and the second pressing buckle are simultaneously pressed to enlarge its width of the buckle hole, the connection portion is separated from the buckle hole, the ejection member ejects the connection portion out of the cavity. The operation of separating the buckle body and the insertion piece only needs to simultaneously press the first button and the second button with one hand.

A detachable belt connector system (100), for the detachable connection of belt ends (770, 775), includes a first connector element (110) with a first connection area (112) and a first belt fastening area (116) and a second connector element (120) with a second connection area (122) and a second belt fastening area (126). The first and second connection areas are configured to be connected to one another in a detachably with a positive-lock. The belt ends can be fastened at the belt fastening areas via a corresponding permanent fastening mechanism. The first belt fastening area and/or the second belt fastening area are configured such that they have a predetermined breaking region (140), by means of which an irreversible break takes place at the belt fastening area having the predetermined breaking region when a predefined limit pulling force (150) is applied at the detachable belt connector system.

A baby carrier may comprise a panel extending upward from the waistband. The panel may extend over a torso of a caretaker, defining an interior space operable to receive a child, forming a seat. The panel may include adjustable fasteners operable to shorten a length of the panel by distributing and securing excess material at or near the bottom of the child, away from the face, minimizing health risks. The panel may couple to shoulder straps having adjustable fasteners to provide a proper fit for various body types. The panel may include adjustable siding operable to slide along the lower portion of each shoulder strap such that the adjustable siding cinches inward toward the panel, narrowing its width, providing a tailored and ergonomic seat.

The present disclosure provides a detachable buckle, including a belt head, a tail clamp, a fixing base, buckle buttons. One end of the fixing base is a hollow slot, the one end of the fixing base is connected with the tail clamp, and at least one socket is disposed on the one end of the fixing base. An opening is disposed on an edge of the hollow slot. Sliding grooves are disposed on both ends of the tail clamp, and the one end of the tail clamp is near the fixing base. Insert blocks sliding along the sliding grooves are disposed inside the sliding grooves. The insert blocks are connected with the buckle buttons, the buckle buttons drive the insert blocks to enter the hollow slot of the fixing base by pushing the tail clamp, and the buckle buttons are fixed with the sockets.

A buckle with a string adjustment portion includes a plug and a socket. The plug includes: a tightening string member attachment portion configured to slidably lock a string member and adjust a length of the string member; and leg portions which are inserted into and engaged with the socket. The socket includes a fitting portion including an insertion opening. An insertion hole through which the string member is inserted is formed to penetrate the tightening string member attachment portion, and a portion connecting the leg portions side of the insertion hole serves as a second bar. The second bar is located on an insertion direction side of the leg portions with respect to a position where an end portion of the plug and the insertion opening of the socket are abutted against each other, in a state where the leg portions are engaged with the socket.

A buckle according to the present invention has two opposing ends that are removably attached to each other using a locking system. On one end of the buckle, the locking system includes two opposing locking pins coupled to a spring that is fully enclosed and protected from external elements. On the other end, corresponding rivets or pin casings with plungers are operable to receive the locking pins and lock the two ends together or push the pins out of the casings to release the buckle. The buckle may also include a plug that is removably attached to the adjustable loop end and allows the central bar of the adjustable loop end to be removed without deforming the central bar. Alternatively, each end of the buckle may include self-aligning tabs that guide the ends of the buckle for fastening and aid in the stability of the buckle.
