The Invention relates to a coupling piece element for a Kenter shackle for anchor chains, which shackle comprises two half elements which can be coupled to one another and between which the coupling piece element can be inserted. The coupling piece element has a base body with at least one transverse borehole. Furthermore two securing bolts are provided, which are mounted in at least one transverse borehole in the base body and can be slidably moved outwards by means of at least one spreader element. The laterally protruding ends of the securing bolts are spherical or conical in shape. The base body has protrusions and/or recesses on its side surfaces facing the half elements for positive guidance on the half elements.

The Invention relates to a Renter shackle for anchor chains, at least comprising two half elements which can be coupled to one another and a coupling piece element that can be introduced between the half-elements wherein the half elements each have an L-shaped or J-shaped configuration, wherein the external toothing having a plurality of parallel toothing planes is formed at the end of a short connection leg and wherein a receiving chamber is formed at the end of a long connection leg, having an internal toothing with a plurality of parallel toothing planes, into which the external toothing of the short connection leg engages, and wherein the connection legs are connected to one another via a curved clasp. In addition, the receiving chamber in the long leg is extended by means of a cavity above the end side of the external toothing of the short leg and/or above the uppermost toothing plane of the internal toothing pointing towards the clasp.

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 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.
