An attachment device includes a first hook and a second hook, the first and second hook, the first and second hook biased towards each other and interconnected with each other, such the first and second hook have a first position, where a first curved end of the first hook does not touch a second curved end of the second hook and a second position, where the first curved end of the first hook does touch the second curved end of the second hook.

A garment hanger has a body for supporting a garment and an attachment mechanism for coupling the garment hanger to a garment rod. The attachment mechanism is mounted on a top central portion of the body and has a first semi-circular ring member, a second semi-circular ring member, a bracket, and a spring means. Each semi-circular ring member has a first end and a central aperture in proximity to a second end. The bracket has a central horizontal portion and two vertical portions on opposite sides of the central horizontal portion. The first and second semi-circular ring members are mounted in a mirrored direction between the two vertical portions by a shaft passing through a central aperture in each of the two semi-circular ring members. The spring means is coupled to force the first ends of the two semi-circular ring members towards each other.

A link connector configured to connect a set of links together. The link connector has a body having an upper portion and a lower portion. A first blocking member is pivotably coupled to the upper portion of the body by a pin member. A second blocking member is pivotably coupled to the lower portion of the body by a pin member. The first and second blocking members are movable between an open position and a closed position such that when in the closed position the link connector forms an 8 shape.

Hanger designed with a built in apparatus which allows it to be placed on a rod from bottom side of rod. Enabling this feature is an apparatus built in the top section of hanger frame. Apparatus built with two rotating semi-circulars, forming a circle when closed, appears like a disc. When hanger is pushed upward against rod, semi-circulars will open and reclose on rod, keeping hanger suspended, allowing it to glide. The instant apparatus will allow hanger to be suspended very close to rod, and will eliminate the old fashion open end hook of prior art.

The present invention discloses a lock catch for pet traction, which comprises a traction hook and a pull ring connected with one end of the traction hook. The traction hook comprises a hook body, an even number of swinging resetting mechanisms and cylindrical pins. The hook body comprises a first connecting part and two installing parts; every two swinging resetting mechanisms form a group and are symmetrically penetrated in corresponding through holes; each swinging resetting mechanism comprises a swinging arm and a torsion spring; one end of each group of swinging arms positioned on the outer side of the installing part is positioned at a lower stopping point, and the other end can be mutually abutted against each other; and open ends limited by the two installing parts and the first connecting part are closed. The present invention has novel appearance, flexible and convenient use and difficult unhooking.

A clasp having two opposing parallel hooks coupled together by a pivot joint. The shank of the first hook is disposed above the plane of rotation while the bend of the first hook is disposed below the plane, and the shank of the second hook is disposed below the plane while the bend of the second hook is disposed above the plane. A protrusion on the first shank engages with a depression on the second shank to latch the clasp in a “closed” configuration. The protrusion engages with an edge of the second shank to latch the clasp in a “crossed” configuration.
