  • the separating element 13 is moved through an opening 21 on the fastening element strip 8.
  • the separating direction 16 is oriented perpendicular to the pressing direction 5, that is to say also perpendicular to the fastening direction, and also perpendicular to the transport direction 11.
  • the isolated fastening element 7 then falls due to gravity through the feed channel 15, which is designed, for example, as a downpipe, up to the receptacle from which it is driven into the ground.
  • the magazine attachment 1 further comprises a stop element 22, which one in the Fig. 4 , 6 and 7 Shown stop position, in which the stop element 22 projects into the transport channel 10 and forms a stop for the fastening element 7 in the transport direction 11 when the fastener 7 is arranged in the separating section, and a passage position in which the stop element 22 outside the transport channel 10 is arranged and allows movement of the fastening element 7 in the transport direction 10 beyond the separating section 12.
  • the stop element 22 is linearly movable between the stop position and the open position. Because each fastening element 7 rests on the stop element 22 after being transported into the separating section 13, an exact positioning of the fastening element 7 is ensured, so that the separation process is less susceptible to faults.
  • the separating device 6 has an actuating element 23 which can be actuated manually by a user of the separating device 6 and which, when the actuating element 23 is actuated, conveys the stop element 22 from the stop position into the open position.
  • the actuating element 23 is rigidly connected to the stop element 22 and, together with the stop element 22, is biased by a stop spring 24 towards the stop position.
