Reduction device (R) with at least one first and at least one second, preferably in each case sleeve-shaped coupling element (K1, K2), which are each adapted for axial placement on the tulip (P8) of a pedicle screw (P1) and which are connected via a lever rod (H2) can be coupled or coupled, which is mounted on the at least one first coupling element (K1) so as to be pivotable and adjustable in angle, and with a preferably bolt-shaped assembly aid (M1) that can be inserted into the at least one first and / or at least one second coupling element (K1, K2), which releasably carries a set screw (S) to be placed in the respective tulip (P8) at its one end section, characterized in that the assembly aid (M1) has an integrated holding device (M4) for the temporary positive or frictional connection with the tulip (P8) for a power transmission between the coupling element (K1, K2) and the tulip (P8).
