Apparatus for coupling a choker line which terminates at a nubbin to a main line in a log-hauling system. The apparatus includes an elongate body having an axially extending chamber of a size enabling confined axial movement of the choker nubbin therein. The choker nubbin and adjacent portion of choker line are receivable in the chamber by passage, in a direction substantially normal to the choker line axis, through an elongate keyhole slot formed in the body and extending to the lower end thereof. A shackle mounted on the upper end of the body for swinging toward and away from a position of axial alignment with the body fastens the body to the main line. A plate formed with the shackle acts to block passage of the choker nubbin through the keyhole slot at all shackle positions except a preselected one which is remote from the aligned position.
