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 quick link has a body defining an open link with two opposite ends. The body comprises a straight portion separating two curved portions. A locking ring is fitted rotating and sliding with respect to the body with a closed position closing the link and an open position where the quick link is open. A shutter is fitted removable with respect to the body. The shutter defines an attachment means fixing the shutter to the straight portion and a blocking system fixing the shutter to the locking ring. The attachment means and blocking system are formed by a ring or a hook. The attachment means and blocking system allow rotation of the shutter with respect to the body when the locking ring is in the open position and prevent rotation of the shutter when the locking ring is in the closed position.

A vertical or block chain connector for linking between two closed chain links includes a lower element and an upper element configured to engage with the lower element to form the chain connector in an assembled condition. In use the lower element is disposed vertically below the upper element in the assembled connector. The upper element is a sliding fit with the lower element and the direction of the sliding connection is in a straight line perpendicular to the longitudinal axis of the connector and in a plane which is parallel to the horizontal axis when the connector is vertically oriented in use.

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.
