An attachment device for arresting a machine member having a substantially cylindrical bore on a cylindrical shaft includes first and second sleeve members adapted to be positioned in a space between the outer surface of the shaft and the inner surface of the bore in the machine member. The two sleeve members have mating, cooperating taper surfaces in the form of a plurality of saw-tooth-shaped axially tapering sections that face one another. At least one of the sleeve members is movable for displacement relative to the other sleeve member to change the radial size of at least one of the sleeve members. The end edge of the first sleeve member projects axially beyond an adjacent end edge of the second sleeve member for receiving an external pushing force causing the first element to be displaced relative to the second element to cause the relative displacement of the sleeve members. The opposite end edge of the second sleeve members engages a stop that may be formed on the machine member.
