Abstract: A fixation arrangement for attachment of an interchangeable part to a retaining device includes a generally circular shaft attached to or integrated with either the interchangeable part or the retaining device, and a generally circular mounting hole formed in the other, a rotary preventing device to prevent rotation of the interchangeable part and the retaining device in relation to each other, and an actuator for tightening the interchangeable part and the retaining device towards each other. The fixation arrangement also includes a sleeve having a wall thickness that tapers along a direction of a center axis of the sleeve, such that an outer envelope surface and/or an inner bore of the sleeve is conically shaped in the direction of its center axis, and which has at least one slit, and a conical portion formed on the inner circumference of the mounting hole and/or on the outer circumference of the shaft.
