Patent ID: 8707984

Claim:
A valve fastening means ( 1 ) for attachment of a hydraulic valve ( 2 ) on a tractor, the hydraulic valve ( 2 ) having at least two screw holes each adapted to receive a screw, the valve fastening means comprising: a tractor part ( 1 a ) adapted to be attached on a tractor; and a valve part ( 1 b ) adapted for direct assembly of the hydraulic valve ( 2 ), the valve part ( 1 b ) comprising at least two slits, of which at least a first slit comprises an opening adapted to let a head of a first screw pass therethrough, and both the first slit and a second of said at least two slits comprise a groove sufficiently narrow to prevent the heads of the first screw and a second screw, respectively, from passing therethrough, but sufficiently wide to allow respective threads of the first and second screws to pass therethrough, the grooves of said at least two slits extending in the same longitudinal direction so that the hydraulic valve ( 2 ), when attached to the valve fastening means without having the first and second screws fully tightened, is movable along the grooves in such way that the first and second screws move in the respective grooves of said at least two slits, wherein the second slit is free of any opening sufficient to permit passage of the head of the second screw, the second slit being displaced from all others of the at least two slits, and wherein the second slit is displaced from respective positions of the at least two screw holes of the valve ( 2 ), whereby the second screw ( 4 ) must be screwed out in order to enable movement of the hydraulic valve ( 2 ) to a position where the first screw extending through the first slit is positioned in front of the opening of the first slit.
