The invention relates to an
assembly tool (1) with a base body (4, 5), optionally a first one, which is essentially designed as a flat part, wherein the base body (4, 5) extends essentially in orientation to a plane (E), wherein a ring
wrench shape (9) is further formed in the base body (4, 5) with an opening axis (A) extending approximately perpendicular to the plane (E) and an access opening (12) formed in one direction of the plane (E), wherein
insertion projections (10, 11) are also provided on the base body (4, 5). Furthermore, the invention also relates to an
assembly tool (1) with a first and a second sub-tool (2, 3).To advantageously design such an
assembly tool, possibly also consisting of a first and a second sub-tool, it is proposed that the
insertion projections (10, 11) can be moved between a working position and a storage position relative to the base body (4, 5) on which they are provided.
