The invention relates to a quick-change device (1) for changing attachments on a construction machine, and comprises a main body (2) and parallel lateral flanks (3) with oppositely disposed first and second bearing bushings (4, 5 [sic; (6, 7)] for receiving mounting pins (8). To expand the range of applications, at least two oppositely disposed first bearing bushings (6) can be inserted at different angular positions into first oppositely disposed passage openings (4) in the lateral flanks (3) by rotating the bearing bushings about an axis (19), which is offset relative to a central axis (21) of a receiving hole (20) of the first bearing bushing (6), and have an external contour (17) for rotationally rigid engagement in a complementary internal contour (18) of the passage opening (4).
