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 transferring gaseous and/or liquid fluids, especially for filling gas tanks of motor vehicles, comprising a sliding sleeve for locking connecting profile sections, especially collet chucks, wherein a data interface, especially a data transmitter, is arranged on the sliding sleeve.

2. A connection coupling according to claim 1, wherein the data transmitter is fastened to the circumferential surface of the sliding sleeve.

3. A connection coupling according to claim 1, wherein a protective tube is arranged between the front housing part and the rear housing part of the connection coupling.

4. A connection coupling according to claim 1, wherein the data transmitter comprises a data line which can be connected with a fluid line.

5. A connection coupling according to claim 3, wherein the data line is guided in the protective tube parallel to the housing.

6. A connection coupling according to claim 1, 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 1, wherein the data transmitter is embedded in a covering of the sliding sleeve.

9. A connection coupling according to claim 1, wherein the data transmitter is arranged as a transponder.
