Surgical instrument which has a main part ( 10 ) with a shaft ( 12 ) and a fixed handle part ( 14 ), on which a moveable handle part ( 20 ) is supported pivotably. The pivotable handle part ( 20 ) engages through a slit ( 18 ) of the main part ( 10 ) and is linked to a slider ( 16 ). The slider ( 16 ) is guided axially shifted on the shaft ( 12 ) so that it cannot be removed. At the proximal end of the work stroke the slider ( 16 ) can be removed from the guide and shaft. Spring tongue ( 50 ) arranged on the pivotable handle part ( 20 ) comes against the main part ( 10 ) when the handle parts ( 14, 20 ) are spread apart and prevents the slider ( 16 ) from entering the cleaning position in which it is released from the shaft ( 12 ). The spring tongue ( 50 ) can be pressed against the moveable handle part ( 20 ) in order to enter the slit ( 18 ) of the main part and to release the locking.
