2. Locking device according to claim 1 , wherein at least three of the selector shafts ( 4 , 5 , 6 , 7 ) are allocated to the shift finger ( 2 a ); wherein the locking finger ( 12 ) positively engages simultaneously in two of the selector shafts ( 4 , 5 , 6 , 7 ) and the shift finger ( 2 a ) positively engages in one of the selector shafts ( 4 , 5 , 6 , 7 ) movable longitudinally by means of the shift finger ( 2 a ); and wherein the locking finger ( 12 ) has a clearance space ( 12 a ) that interrupts the locking finger ( 12 ) in the pivoting direction of the locking finger ( 12 ) and located, upon fixing two selector shafts ( 4 , 5 , 6 , 7 ) which are directly adjacent to the longitudinally freely movable selector shaft ( 4 , 5 , 6 , 7 ), directly over the slot ( 4 b ) of the longitudinally freely movable selector shaft ( 4 , 5 , 6 , 7 ); and wherein the selector shaft ( 4 , 5 , 6 , 7 ) freely movable with the shift finger ( 2 a ) passes through the locking finger ( 12 ) at the clearance space ( 12 a ) without contact with the locking finger ( 12 ).

3. Locking device according to claim 2 , wherein the shift finger ( 2 a ) is supported between a first wall and a second wall opposite the first wall of the casing ( 10 , 31 ) with a pivot stud ( 8 ) having the pivot axis ( 9 a , 34 ); wherein at least one of the walls has a support eyelet ( 10 a ) for supporting the pivot stud ( 8 ).

4. Locking device according to claim 3 , wherein the tilt axis ( 9 a , 34 ) and the pivot axis ( 8 a , 36 ) run mutually spaced apart.

5. Locking device according to claim 4 , wherein the casing ( 10 , 31 ) is pivotably supported on the housing ( 3 ) by means of two mutually opposite pivot studs ( 9 ); wherein the mid-axes of the pivot studs ( 9 ) and the tilt axis ( 9 a ) coincide; and wherein the pivot studs ( 9 a ) engage in support eyelets ( 10 b ) on the casing ( 10 , 31 ).

6. Locking device according to claim 5 , wherein the tilt axis ( 9 a , 34 ) and the pivot axis ( 8 a , 36 ) run mutually spaced apart.

7. Locking device according to claim 2 , wherein the casing supports, in a support arrangement ( 1 , 29 ), a shift lever ( 2 , 35 ) pivotably around the pivot axis ( 8 a , 36 ) with respect to the casing; and wherein the support arrangement ( 1 , 29 ) supports the shift lever ( 2 , 35 ) with the casing, pivotably around the tilt axis ( 9 a , 34 ) aligned transversely of the shift axis ( 8 a , 36 ), with respect to a housing ( 3 ); and wherein the shift lever ( 2 , 35 ) has a free end upon which the shift finger ( 2 a ) is located and is pivotable about the tilt axis ( 9 a , 34 ) and the pivot axis ( 8 a , 36 ).

8. Locking device according to claim 7 , wherein the tilt axis ( 9 a , 34 ) and the pivot axis ( 8 a , 36 ) run mutually spaced apart.
