A tamper-evident, single use, ring assembly, is assembled from first and second interengaging broken rings (1, 2). The first broken ring (1) is of a first material and the second broken ring (2) is of a second material. A break in the ring of the first material is offset circumferentially from a break in the ring of the second material. The assembly of the rings forms a closed ring assembly which can be cut through in the region of the break in the ring of the first material to open the ring assembly. At least one of the rings (1, 2) of the ring assembly is resiliently stressed in its assembled state such that, upon cutting through of the ring assembly, the confronting ends of the assembly move apart.

A key ring includes a body having an upper ring and a lower ring, the upper ring having a closable opening. The upper ring and the lower ring are separated by a pinch point. The pinch point includes a first and second side of the body, the first and second sides of the body in very close proximity at the pinch point, such that a key sliding along the lower ring of the body may not easily pass the pinch point to the upper ring.

Provided herein is a low-profile key ring including a planar body including first and second inflection points, a connecting section extending between the first and second inflection points to define a concave indentation of the planar body, and a split disposed in the connecting section to define an outer segment and an inner segment of the connecting section, wherein the outer segment and inner segment are complementarily contoured.

A press control key ring includes a split ring defining an opening between two opposite ends thereof, and a locking module including an inner casing for the insertion of the two opposite ends of the annular wire rod and having a mounting hole on the middle of the top wall thereof, an elastic member mounted in the inner casing with one end thereof secured to an inner bottom wall of the inner casing, a press block mounted in the mounting hole and supported on the opposite end of the elastic member, and an outer casing sleeved onto the inner casing and having an insertion hole on the middle of the top wall thereof for the insertion of the press block.

Provided herein is a low-profile key ring including a planar body including first and second inflection points, a connecting section extending between the first and second inflection points to define a concave indentation of the planar body, and a split disposed in the connecting section to define an outer segment and an inner segment of the connecting section, wherein the outer segment and inner segment are complementarily contoured.

A dual-entry keyring includes a ring body in a two-turn ring shape design, defining a first end and a second end respectively disposed at opposing top and bottom sides thereof beyond superimposition and a first press portion and a second press portion arranged between the first end and the second end to face toward each other and respectively outwardly curved so that a gap is defined between the first press portion and the second press portion. Further, the part of the first turn of the two-turn ring shape design of the ring body beyond the first press portion is closely abutted to the part of the second turn of the two-turn ring shape design of the ring body beyond the second press portion so that a stress point is formed at each of two opposite lateral sides of the gap between the first press portion and the second press portion.

A key chain includes a bisected hollow cylinder, one side of the bisected hollow cylinder forming a first side and another side forming a second side. The key chain further includes a first holder, the first holder having a first half cylindrical body, the first holder located inside of the first side of the bisected hollow cylinder, such that a first outer radius of the first holder is coextensive with a first inner radius of the second side when interconnected. The key chain further includes a second holder, the second holder having a second half cylindrical body, the second holder located inside of the second side of the bisected hollow cylinder, such that a second outer radius of the second holder is coextensive with a second inner radius of the first side when interconnected. The key chain further includes a first magnetic material and second magnetic material, the first magnetic material located in the first holder and the second magnetic material located in the second holder, the first magnetic material and the second magnetic material oriented such that when the first side and the second side are proximate to forming a complete cylinder, the first holder is guided to the second holder through magnetism between the first magnetic material and the second magnetic material.

A rotatable connector formed from two parts, each comprising a body extending from a connecting head having a first face and an opposed second face, the second face having an arcuate tail section on an outer perimeter edge and shaped to be received by a tail socket defined between the first face and a pin extending from a proximal end of the body. When the two parts are engaged, the connecting heads are coaxial to define an axis of rotation. When the parts are rotated on the axis relative to one another, the tail section of the first part travels through the tail socket of the second part and the tail section of the second part travels through the tail socket of the first part, thereby connecting the two parts together. When the parts are rotated in the opposite direction, the parts are disconnected from each other.

A tamper-evident, single use, ring assembly, is assembled from first and second interengaging broken rings (1, 2). The first broken ring (1) is of a first material and the second broken ring (2) is of a second material. A break in the ring of the first material is offset circumferentially from a break in the ring of the second material. The assembly of the rings forms a closed ring assembly which can be cut through in the region of the break in the ring of the first material to open the ring assembly. At least one of the rings (1, 2) of the ring assembly is resiliently stressed in its assembled state such that, upon cutting through of the ring assembly, the confronting ends of the assembly move apart.

A key ring includes a fixing portion, a connecting portion and an operating portion connected in sequence, where the fixing portion is provided with an internally threaded rod extending to one side thereof, and an outer side wall of the internally threaded rod is configured for hanging a key; the operating portion is provided with an operating knob, the operating knob is rotatably mounted on the operating portion, the operating knob is provided with an externally threaded rod, and the externally threaded rod is in threaded connection with the internally threaded rod; the key ring provided by the present disclosure has the feature of convenient operation.
