The invention relates to an arrangement for fixing an add-on piece (1), e.g. an excavator shovel, to a boom (2) of a shovel in a replaceable manner. According to the invention, two parallel holding bolts (3, 4) are arranged o n the add-on piece (1) and can be gripped by grippers (6, 7) that can be displaced in relation to each other and are arranged on a holding element (5 ) on the boom (2) of the shovel. Said grippers (6, 7) comprise at least partially open insertion openings (8, 9) for the holding bolts (3, 4). One gripper (6) is connected to the holding element (5) in a fixed manner and on e (7) can be held in a guide of the holding element in a linearly displaceable manner. Spring elements (11) acting in the closing direction of the gripper (7) are associated with the linearly displaceable gripper (7). An insertion opening (8) which is open in the direction of an imaginary plane through the axes of the holding bolts (3, 4) is provided on the fixed gripper (6), and a n abutment (12) which is oriented at least approximately at right angles to th e imaginary plane, at a distance matching the distance (A) between the holding bolts (3, 4), is provided on the holding element (5) as an insertion part fo r the second holding bolt (4). The displaceable gripper (7) comprises a hook- shaped section (13)for at least partially gripping the second holding bolt (4).
