The invention relates to an
assembly tool (1) having a possibly first main body (4, 5) formed substantially as a flat part, wherein the main body (4, 5) extends substantially oriented on a plane (E), wherein, furthermore, a ring spanner-shaped moulding (9) with an opening axis (A) extending approximately perpendicularly in relation to the plane (E) and with an access opening (12) formed in a direction of the plane (E) is formed in the main body (4, 5), wherein plug-in projections (10, 11) are also provided on the main body (4, 5). Furthermore, the invention also relates to an
assembly tool (1) having a first and a second part-tool (2, 3). For the advantageous design of such an
assembly tool, possibly also consisting of a first and a second part-tool, it is proposed that the plug-in projections (10, 11) can be displaced relative to the main body (4, 5), on which they are provided, between a working position and a storage position.
