Abstract

The aim of the invention is to increase security when connecting a connective coupling (10) used for transferring gaseous and/or liquid fluids, especially for filling motor vehicle fuel tanks, provided with a sliding sleeve (18) in order to lock connecting profile sections, especially collets (15). According to the invention, a data interface, especially a data transmitter (60), is arranged on the sliding sleeve (18).

Claims

1. A connection coupling for connecting to a nipple of a tank of a motor vehicle, the connection coupling comprising:

a front housing part;

a sliding sleeve for locking connecting profile sections of the connection coupling onto the nipple, the sliding sleeve being movable in a longitudinal direction with respect to the front housing part; and

a data interface arranged on the sliding sleeve and configured to indicate matching of the connection coupling with the nipple, at least a portion of the data interface being movable in the longitudinal direction with the sliding sleeve.

2. A connection coupling according to claim 1, wherein the profile sections are collet chucks.

3. A connection coupling according to claim 1, wherein the data interface is a data transmitter.

4. A connection coupling according to claim 3, wherein the data transmitter comprises a data line which can be connected with a fluid line.

5. A connection coupling according to claim 4, wherein the data line is guided in the protective tube parallel to the housing.

6. A connection coupling according to claim 3, wherein the data transmitter is provided with a ring-like configuration and is arranged around the sliding sleeve.

7. A connection coupling according to claim 6, wherein the data transmitter is shrunk onto the sliding sleeve.

8. A connection coupling according to claim 3, wherein the data transmitter is embedded in a covering of the sliding sleeve.

9. A connection coupling according to claim 3, wherein the data transmitter is arranged as a transponder.

10. A connection coupling according to claim 3, wherein the data transmitter is fastened to a circumferential surface of the sliding sleeve.

11. A connection coupling according to claim 3, wherein a protective tube is arranged between the front housing part and a rear housing part of the connection coupling.
