Devices, systems, and methods of operating the same are described. The method may include attaching a first loop of a male connector to a first end of a first plug. The method may include attaching a second loop of a female connector to a second end of a second plug. The method may include connecting a first end of the first plug to the second end of the second plug. The method may include connecting a male fastener of the male connector to a female fastener of the female connector.

A strap connection member is disclosed. The strap connection member includes a pair of ring-shaped strap hangers provided at one side of a base and integrally formed so as to be spaced apart from each other. Therefore, the strap connection member may simply fix straps or connect straps such that the lengths of the straps are adjustable, and simultaneously connect two or more straps in different directions.

An elastic cord terminating in a pair of hook devices, each hook device made from a continuous length of wire. The continuous length of wire at one end has a hook bend having a hook tip, and at the other end a cord attachment. The hook bend and the cord attachment are separated by a shank length of the continuous wire into which there is bent a closed finger loop. The finger loop has a hook proximate surface that is separated longitudinally from the hook tip and toward the cord attachment by a selectable clearance distance.

A strap system for a motorcycle helmet that includes: a first earflap on the helmet; a second earflap on the helmet, where the second earflap includes a receiving ring; a chin strap extending from the first earflap; a pair of hook and loop connectors on the chin strap; and a securing button at one end of the chin strap. The second earflap includes an opening adapted to receive the chin strap, where the receiving ring is a D-ring.

A weightlifting belt includes a flexible strap portion with a first major surface (e.g., a front), a second major surface (e.g., a back), a first longitudinal end, a second longitudinal end, a first lateral side, and a second lateral side. An anchor assembly is in contact with the first major surface of the flexible strap portion near the first longitudinal end of the flexible strap portion. A lever-actuated hook assembly is in contact with the first major surface of the flexible strap portion near the second longitudinal end of the flexible strap portion. The lever-actuated hook assembly is configured to engage the anchor assembly so as to hold the first longitudinal end of the strap portion close to, or in physical contact with, the second longitudinal end of the strap portion so as to form a loop that can fit around a waist of a human.

A connector includes a frame having a first end, a second end, and a pass-through opening extending between the first end and the second end along a longitudinal axis of the frame. The connector further has a gate positioned between the first end and the second end of the frame and movable between a closed position to close the pass-through opening and an open position to open the pass-through opening. A locking mechanism selectively locks the gate in the closed position. The locking mechanism has a rotatable knob connected to at least one of the first end and the second end of the frame and rotatable in a direction about the longitudinal axis, and a locking indent on the gate configured for receiving at least a portion of the rotatable knob when the gate is in the closed position. The rotatable knob is rotationally biased by a biasing mechanism.

The fixing buckle comprises first and second securing parts provided with coupling elements one of which defines a hook. A closure system is configured to define a first position preventing extraction of the first coupling elements from the second coupling elements and a second position allowing insertion and extraction of the first coupling elements. The closure system comprises first and second closure plates each having a first position obstructing the hook and a second position configured to remove the first coupling elements. The first position of the first closure plate is configured to prevent movement of the second closure plate from its first position to its second position. The second closure plate separates the first coupling elements and the first closure plate along an extraction channel defined by the hook.
