  • the mode of operation of the setting head 10b is essentially such that in each case a clip nut 1 is introduced into the loading position of the part 35 into the provision position 17b there. Subsequently, the part 35 in the in the FIG. 7 indicated by broken lines working position moves in which the guide 37 forms a support for the rear end 1.2 of the respective clip nut 1, so that they can then be pushed back by relative movement between the workpiece 8 and the setting head 10b on the workpiece.
  • the setting head 10b has the advantage that its effective length in the working position is determined only by the axial length of the relatively short part 35, so that with the setting head 10b and the sliding of clip nuts 1 not only at the edge region of a workpiece 8, but for example the edge region, for example, the closed edge region of a recess formed within the workpiece 8 is possible.
  • the change-lock 22 not mechanically, but in other ways, for example, to realize pneumatically. In this case, in particular, it is also possible to design the feed element such that it is moved out of the channel 12 by the conveying air for the passage of the respective clip nut 1.
