摘要

A COUPLING HOOK FOR A GUIDE MEMBER OF A TRACTOR THREE POINT ATTACHMENT A coupling hook has a latch bolt slidable in a bore in the hook so as to be displaceable into the hook opening. A locking bolt is pivotally attached to the latch bolt and is acted upon by a locking spring in a direction so as to intersect the axis of the locking bolt and the bore. The locking bolt has a locking surface which under the force of the locking spring is engaged with an abutment surface when the latch bolt is in the locked position.
