1. A protective device comprising: a membrane and a support device for the membrane, wherein the support device comprises an inflatable first support element with a flexible wall which forms a first pressure chamber, wherein the first support element has a first connection port with a first connection opening, wherein the support device has an inflatable second support element with a flexible wall which forms a second pressure chamber, wherein the second support element has a second connection port with a second connection opening, wherein a connection device for connection the first connection port to the second connection port is provided, wherein the connection device has a first connection part for connecting to the first connection port and a second connection part for connecting to the second connection port, wherein the first connection part comprises a main body having two outer threaded cylindrical portions with the first outer threaded cylindrical portion having a smaller radius than the second outer threaded cylindrical portion, wherein the first and second connection parts are connectable to one another in a detachable manner, wherein the connection device has a valve adapted to shut off the first connection opening, wherein the valve comprises a movable valve body, a valve seat and a biasing member which urges the valve body against the valve seat, wherein the second connection part has an actuating element which is arranged in such a manner that it moves the valve body from a closed position to an opened position if the second connection part is attached to the first connection part. 2. The protective device according to claim 1, wherein the movable valve body comprises a sealing element abutting against the valve seat. 3. The protective device according to claim 1, wherein the first connection part comprises a socket, in which the valve body is at least partially arranged thereby. 4. The protective device according to claim 3, wherein a stop for the spring is arranged in the socket. 5. The protective device according to claim 3, wherein the first connection part has a main body, on which the socket is arranged. 6. The protective device according to claim 1, wherein the second connection part has a socket. 7. The protective device according to claim 6, wherein the second connection part has a main body on which the socket is arranged. 8. The protective device according to claim 1, wherein the actuating element has at least two inwardly facing protrusions that are spaced apart on the second connection element. 9. The protective device according to claim 1, wherein a first seal is provided which seals the first connection part with respect to the first connection port. 10. The protective device according to claim 1, wherein a second seal is provided which seals the second connection part with respect to the second connection port. 11. The protective device according to claim 1, wherein a third seal is provided which seals the main body of the first connection part with respect to the main body of the second connection part. 12. The protective device according to claim 1, wherein at least one of the first support element and the second support element has a port element which forms the first or second connection port. 13. An inflatable support structure for covering by a membrane, the inflatable support structure comprising: an inflatable first support element with a flexible wall which forms a first pressure chamber, wherein the first support element has a first connection port with a first connection opening and a valve which is adapted to close the first connection opening, wherein the valve comprises a valve body, a valve seat and a biasing member which urges the valve body against the valve seat, wherein the support structure comprises an inflatable second support element with a flexible wall which forms a second pressure chamber, wherein the second support element has a second connection port with a second connection opening, wherein the first and second connection ports are connectable to one another in a detachable manner, wherein the first connection port comprises a main body having two outer threaded cylindrical portions with the first outer threaded cylindrical portion having a smaller radius than the second outer threaded cylindrical portion, wherein when connected the first and second connection ports form a connection device, wherein when the first and second connection ports are connected to one another the valve is opened, and the first and second pressure chambers are inflatable through a single inflation port. 14. The support structure according to claim 13, wherein the valve body comprises a sealing element abutting against the valve seat. 15. The support structure according to claim 13, wherein the first connection port comprises a socket, in which the valve body is at least partially arranged thereby. 16. The support structure according to claim 13, further comprising a membrane adapted to cover the first and second support elements. 17. The support structure according to claim 13, wherein the biasing member is a spring.
