A bicycle-chain outer link plate comprises a first outer-link end portion, a second outer-link end portion, and a first outer-link intermediate portion. The first outer-link end portion comprises a first outer-link opening and a first outer-link end outermost edge. The second outer-link end portion comprises a second outer-link opening and a second outer-link end outermost edge. The first outer-link intermediate portion comprises a first outer-link intermediate outermost edge and a first additional outer-link intermediate outermost edge. The first outer-link intermediate portion has a first distance defined in an axial direction on a first outer-link longitudinal axis. The first outer-link intermediate outermost edge has a second distance defined in the axial direction. The first outer-link end outermost edge has a third distance defined in the axial direction. The first distance is larger than the second distance and the third distance. The second distance is larger than the third distance.

A breakaway chain having a breakaway connector and first and second chain portions is provided. The breakaway connector includes a first opening is defined between a first wall portion and a second wall portion spaced away from the first wall portion. A first flexible gripping member extends from the first wall portion towards the second wall portion. A second opening is defined between a third wall portion and a fourth wall portion spaced away from the third wall portion. A second flexible gripping member extends from the third wall portion towards the fourth wall portion. The first chain portion has a first chain link. The first chain link inserts into the first opening and engages the first flexible gripping member. The second chain portion has a second chain link. The second chain link inserts into the first opening and engages the second flexible gripping member.

A swivel connection device having a housing body, two coupling elements connected to the housing body, and hinged connection elements connected to the housing body is provided. The two coupling elements are freely rotatable relative to one another about a main rotation axis defined by the hinged connection elements. Each coupling element, in an operating configuration, supports a respective load directed along a respective load direction substantially parallel to the main rotation axis. The housing body defines a plurality of connection seats, and each connection seat defines a stop wall. Each of the two coupling elements is inserted into a respective connection seat, against a respective stop wall, along an insertion direction. The insertion direction of each coupling element is in a direction concordant with the load direction of the load supported by a same coupling element.

A Irreversibly Locking Clip. The clip has a hinged latch that pivots from an open position to a closed position, similar to a conventional caribiner. The clip provides the structural strength and durability of a caribiner or shackle. The clip includes one or more spring-loaded pins that will irreversibly lock the latch in a closed position by extending into a corresponding socket when the latch is closed. Additionally, the clip incorporates a retaining tip at the tip end of the latch that engages a tip retaining socket when the latch is closed in order to provide additional reinforcement between the latch and the body of the clip.

A clip composed of two similar hooks, pivoting around a common axis, and facing each other. Hooks are biased toward each other around the common pivot by a torsion spring. The two hooks form a loop that retains a dog collar D ring. The tips of the hooks overlap each other, allowing each hook to carry half the load. Finger pads are positioned opposite the hooks, such that when pressure is applied to the finger pads, the hooks are separated, and an ejector tab forces the dog collar D ring into the opening between the hooks, releasing the dog collar D ring. This clip is cold temperature tolerant.

The invention relates to the field of anchor chains, and more particularly an anchor chain (1) comprising a first plurality of links (3) and, at the end of the chain, a second plurality of links (4) comprising at least three successive links (4) in each of which at least one property selected from its bar diameter and the elastic limit of its material is substantially greater than in each of the links (3) of the first plurality, in order to improve the ability of the chain to withstand fatigue by bending of the links (4) in the second plurality.

A block lock for connecting two chain ends is disclosed including two opposing block lock halves extending in the longitudinal direction when the block lock is in the locked state, which interlockingly engage in each other, and which lock to form at least one receiving opening for receiving a chain link. The block lock halves are pivotably coupled together in the region of a pivoting end such that the block lock halves can be shifted into an open position or locked position by performing the pivoting movement. In the locked position, the block lock halves integrally engage in one another at an opposite locking end and can be locked.
