A breakable coupling in a load coupling (1) which fits complementarily in a coupling holder (2), the load coupling (1) comprising a locking-dog casing (13), which is connected to a load attachment (12), and being formed with locking dogs (132) which are movable between a non-locking position and a locking position, and a locking-dog blocking element (15) being movable between a blocking position, in which the locking dogs (132) are prevented from being moved out of their locking positions, and a non-blocking position, and the load attachment (12) being locked to the locking-dog casing (13) by means of a shear pin (14) having a weakened middle portion (144) and being dis- placeable between a normal position, in which it forms a connection between the load attachment (12) and the locking-dog casing (13) by first and second end portions (141, 142), and a release position, in which the first end portion (141 ) has been pulled away from the load attachment (12) and into the locking-dog casing (13) and the weakened middle portion (144) is arranged in an interface between the load attachment (12) and the locking-dog casing (13).
