A fluid line for connection with an assembly of a motor vehicle includes a pipe and at least one connector. The connector is configured for insertion into a complementary coupling, and has a main body and a locking element for locking with the coupling. The locking element is mounted relative to the main body so that it can rotate around a rotational axis, and designed in such a way as to achieve a locking of the connector by rotating the locking element around the rotational axis. The locking element has at least one locking contour, and is designed in such a way that a force acting axially on the connector is exerted in the direction of the coupling by rotating the locking element during a locking process with a coupling.
