A snap hook with front and rear locks that must be disengaged for the gate to open. The body has a base and a J-shaped hook. A gate has two parallel, spaced fingers extending from an end of a gate arm. As the gate pivots between open and closed positions, a stop pin extending between the arms and through a curved slot in the body slides within the curved slot. A front lock pivots between a locking position, where shoulders in the gate arms abut an edge on the front lock, preventing the gate from pivoting open, and an unlocking position, where the shoulder does not abut the front lock edge. The rear lock pivots between a locking position, where the curved slots on the rear lock are not aligned with body curved slot, and an unlocking position, where the curved slots are aligned, and the gate can pivot open.

Two rigid fasteners each with integrally coupled magnets of opposing polarity on an outer surface thereon. The rigid fasteners also each have a spring-loaded displaceable clip member rotatably coupled thereto, wherein the clip member is operably configured to open and close to provide access to an aperture defined by the rigid fasteners. The fasteners are coupled together with a tether member also of a rigid material, wherein the fasteners are configured to selectively couple and uncouple together with the magnets thereon.

A linkless, locking snap-hook, comprising a body member with a proximal hook, defining a proximal opening facing a first direction, and a distal hook, defining a distal opening facing a second direction. A linkless, locking snap-hook also comprising a locking mechanism which has a keeper, a biasing means, and a locking grip member. The linkless, locking snap-hook is capable of accepting a variety of attachment devices.

A 360-degree double carabiner includes an outer-carabiner, an inner-carabiner and a swivel joint including a swivel cylinder and two locking pins. The outer-carabiner is enabled into a horizontal hole, the inner-carabiner is enabled into a vertical hole, the two locking pins are enabled into two smaller holes of the swivel cylinder to lock the outer-carabiner and the inner-carabiner to the swivel cylinder. The 360-degree double carabiner includes an outer latch, wherein one end of the outer latch is fixed to a proximal end of the outer-carabiner and another end of the outer latch rests on a distal end of the outer-carabiner. The 360-degree double carabiner includes an inner latch, wherein one end of the inner latch is fixed to a proximal end of the inner-carabiner, another end of the inner latch rests on a distal end of the inner-carabiner.

Embodiments are directed to a carabiner that includes a carabiner body forming an opening and comprising a gate base, a gate rest, and a gate rest extension. In embodiments, at least one pivotable gate is coupled to the gate base at a pivotable point and adapted to contact the gate rest when in a closed position. In embodiments, the gate rest extension comprises a gate rest extension axis, and an angle between the gate rest extension and gate when in the closed position is approximately 35-61 degrees.

Embodiments are directed to a carabiner that includes a carabiner body forming an opening having a width, the carabiner body including a gate rest notch, and a gate rest. The carabiner further includes a pivotable gate coupled to the carabiner body at a pivotable point and adapted to contact the gate rest notch when in a closed position. The carabiner body is sized to accommodate an object with an aperture and a thickness, and the width is approximately less than 100% greater than the thickness.
