A fastening device for securing a tool on an adjustable crossbar of a waste stripping and blank separating station of a sheet processing machine includes a tie bar provided with a headed end which receives a support for the tool part, a pair of clamping jaws, each of which is provided with a supporting surface designed to enter in contact with the crossbar of the stripping station and have additional supporting surfaces designed to enter into contact with one another. The second end of the tie bars carries a tightening arrangement which provides three positions including a substantial release of pressure on the jaws to enable fixing and dismantling of the tool, an intermediate amount of pressure on the jaws to allow shifting of the arrangement along the crossbar and a third amount of pressure which provides a tightening or locking of the tool in a given position on the crossbar. |
