Tool for fastening an article, in particular a cable harness, by means of a band to be closed by a lock (10), which has, at a front surface of its tool body (1), a wraparound clamp (4) formed at least partially of clamp parts (5) movably held at the tool body (1), a lock mount (9), a tensioning device for tensioning the band guided in the wraparound clamp (4) and through the lock (10), and a control device for opening the wraparound clamp (4) and tensioning the band, in which the control device is designed in such a way that, before the completion of the tensioning of the band, the wraparound clamp (4) is opened and is retracted through a substantial part of its forward overhang. Furthermore, in the case of an arrangement for fastening an article, in particular a cable harness (12), with the enclosing of a securing lug (7) by means of a flexible band, there is provided a tool which forms a wraparound guide, formed at least partially of clamp parts (5) movably held at the tool body (1), for guiding the band around the article (12), in which the free ends (49) of the clamp parts (5) adjoin the securing lug (7) in their closed condition and the latter forms a part of the wraparound guide.
