Abstract

The invention relates to a method, wherein a line connector (1), in particular a plug connector, by a fastening device (2) is fastened to a line (3) for liquid and/or gaseous media, wherein during or after the fastening of the line connector (1) to the line (3), a blocking body (4) already present on the line connector (1) and/or on the line (3) is removed from the line connector (1) and/or from the line (3) by means of the fastening device (2), wherein the blocking body (4) prevents a mating connector (5) from being connected to the line connector (1) as long as the blocking body is present on the line connector (1) and/or on the line (3).

Claims

1-10. -10. (canceled)

11. Method in which a line connector (1), in particular a plug connector, by a fastening device (2) is fastened to a line (3) for liquid and/or gaseous media, wherein during or after the fastening of the line connector (1) to the line (3), a blocking body (4) already present on the line connector (1) and/or the line (3) is removed from the line connector (1) and/or the line (3) by means of the fastening device (2), with the blocking body (4) preventing a mating body (5) from being connected to the line connector (1) as long as the blocking body is present on the line connector (1) and/or the line (3).

12. Method according to claim 11, wherein the fastening device (2) has at least one deformation tool (6), with at least sections of the line connector (1) and/or the line (3) being, preferred plastically, deformed by the deformation tool (6) in order to fasten the line connector (1) to the line (3).

13. Method according to claim 12, wherein the blocking body (4) is removed from the line connector (1) and/or from the line (3) by means of the deformation tool (6).

14. Method according to claim 12, wherein the line (3), preferably one end section (7) of the line (3), is inserted into a mounting cavity (10) limited by walls (8, 9), particularly of the line connector (1), with preferably being provided that at least one of the walls (8, 9) limiting the mounting cavity (10) is, preferably together with the line (3) or its end section (7), preferably plastically, deformed by means of the deformation tool (6).

15. Method according to claim 11, wherein before the removal of the blocking body (4), the fastening device (2) checks by means of at least one control parameter, whether the line connector (1) has been fastened to the line (3).

16. Method according to claim 15, wherein the or at least one of the control parameters is a parameter characteristic for the fastening process and/or wherein the or at least one of the control parameters is to check whether the line (3) is present.

17. Method according to claim 16, wherein forces and/or stretches of way used in or on the fastening device, preferably by the deformation tool (6), are consulted as control parameter characteristic for the fastening process during the fastening process, preferably deformation process.

18. Method according to claim 11, wherein for removing the blocking body (4) from the line connector (1) and/or from the line (3) by means of the fastening device (2), preferably by means of the deformation tool (6), the blocking body (4) is drawn off and/or screwed off and/or cut off and/or broken off the line connector (1) and/or the line (3) and/or the removal of the blocking body (4) is effected by means of the fastening device (2), preferably by means of the deformation tool (6), by means of, preferably plastic, deformation of the line connector (1) and/or the line (3).

19. Line connecting device or (1), in particular for a method according to claim 11, comprising a line connector (1) and a mating connector (5) that can be connected to the line connector (1) in particular by plugging or screwing, wherein the line connector (1) has a blocking body (4) in a region, wherein a section of the mating connector (5) is positioned after the connection to the line connector (1) when the blocking body (4) is removed, so that the blocking body (4), as long as it is present on the line connector (1), prevents a mating connector (5) from being connected to the line connector (1) and that the blocking body (4) can be removed from the line connector (1), preferably without deforming other components of the line connector (1).
