A forked thill head attachment for installing a forked thill to a sail mast of a rigging comprises a forked thill head (1) which, in a top view, is constructed essentially V-shaped, and opposed clamping jaws for gripping about the mast having a rearward vertical gap (17). In order to produce a firm connection between a forked thill and a mast for a rigging, that can be firmly locked and released with little expenditure of force, the clamping jaws (13) are constructed as a separate component from the forked thill head (1) and held by a longitudinal bolt (21) guided through the forked thill head (1) in the longitudinal direction in the plane of longitudinal symmetry. Locking rotation of the screw member provided at the forward outer side of the forked thill head (1) over the longitudinal bolt (21), moves clamping jaws (13) in the longitudinal direction while contacting, in the forward direction, contacting surfaces (11) likewise running, in a top view, V-shaped to one another. A still further simplified manipulation can be achieved (FIG. 5) by an additional quick-locking lever (51).

A forked thill head attachment for installing a forked thill to a mast of a rigging, with a V-shaped forked thill head, clamping jaws for gripping about the mast and forming a rearward vertical gap, said clamping jaws being constructed as a separate component from the forked thill head for detachable mounting to the mast together with a forward lying adjustment section of the forked thill head by a longitudinally alterable screw contrivance provided in the forked thill head in the region of the vertical longitudinal plane of symmetry of the clamping jaws, rotation of the adjustment section displacing the clamping jaws in the forward direction and pressing them toward one another, characterized in that said screw contrivance includes a longitudinal bolt running through the forked thill head in the longitudinal direction and joining the clamping jaws with respect to said adjustment section, said bolt being threaded such that rotating said screw contrivance presses said adjustment section and the clamping jaws toward one another, with said jaws contacting forwardly tapered inner contacting surfaces of an accommodating space of the forked thill head, said clamping jaws pivoted over a tilting axis lying perpendicularly to the vertical longitudinal plane of symmetry of the forked thill, wherein said clamping jaws are provided, substantially in the vertical plane of longitudinal symmetry, with a boring that is penetrated by the longitudinal bolt, with the clamping jaws being held by a bolt head integral with said bolt and having a larger diameter as compared to the inner diameter of the boring in the clamping jaws.
