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. A method of fastening comprising:

fastening by a fastening device a line connector to a line for liquid and/or gaseous media,

wherein during or after the fastening of the line connector to the line, a blocking body already present on the line connector and/or the line is removed from the line connector and/or the line via the fastening device, with the blocking body preventing a mating body from being connected to the line connector as long as the blocking body is present on the line connector and/or the line.

2. The method according to claim 1, wherein the fastening device has at least one deformation tool, with at least sections of the line connector and/or the line being deformed by the deformation tool in order to fasten the line connector to the line.

3. The method according to claim 2, wherein the blocking body is removed from the line connector and/or from the line via the deformation tool.

4. The method according to claim 2, wherein the line is inserted into a mounting cavity limited by walls of the line connector.

5. The method according to claim 1, wherein before the removal of the blocking body, the fastening device checks via at least one control parameter, whether the line connecter has been fastened to the line.

6. The method according to claim 5, wherein the at least one control parameter is a parameter characteristic for the fastening process and/or wherein the at least one control is to check whether the line is present.

7. The method according to claim 6, wherein forces and/or stretches of way used in or on the fastening device are consulted as control parameter characteristic for the fastening process during the fastening process.

8. The method according to claim 1, wherein for removing the blocking body from the line connector and/or from the line via the fastening device, the blocking body is drawn off and/or screwed off and/or cut off and/or broken off the line connector and/or the line and/or the removal of the blocking body is effected via the fastening device via deformation of the line connector and/or the line.

9. A line connecting device comprising:

a line connector;

a blocking body, which is detachably coupled to the line connector and can be removed from the line connector; and

a mating connector which can be connected to the line connector

wherein

when the blocking body is coupled to the line connector, the blocking body is configured to prevent the mating connector from being connected to the line connector.

10. The line connecting device according to claim 9, wherein the mating connector can be connected to the line connector by plugging.

11. The line connecting device according to claim 9, wherein the mating connector can be connected to the line connector by screwing.

12. The line connecting device according to claim 9, wherein the blocking body can be removed from the line connector without deforming other components of the line connector.

13. The line connecting device according to claim 9, wherein the line connector has a recess in which the blocking body is disposed.

14. The line connecting device according to claim 13, wherein the recess is positioned in an inner wall of the line connector.

15. The line connecting device according to claim 9, wherein the blocking can be withdrawn from the line connector in an axial direction of the line connector.

16. The line connecting device according to claim 13, wherein the blocking body has a protrusion and the recess has a holding grove which corresponds with the protrusion wherein the blocking body is slideable connected to the line connector.
