Abstract
The invention relates to a block lock for connecting two chain ends which comprises two block lock halves which extend in the longitudinal direction and which engage with each other in a positive fit via pins and grooves and lock to form two seating openings, each one to receive a chain link. The seating openings are separated by a crossbar which extends from one of the block lock halves to the opposite block lock half, wherein the block lock halves are coupled so as to rotate about the crossbar and/or on an end of a block lock half, a pin which protrudes in the direction of the opposite block lock half, which engages laterally in one lateral seating groove formed on one end of the opposite block lock half, when carrying out a relative rotational movement of both block lock halves.
