Abstract: A heatable fluid line having a pipeline and an electrical heat conductor extending at least over a section of the pipeline. The pipeline has at least two longitudinal sections that are configured differently in respect of the material properties and/or design thereof. At least one first longitudinal section is formed of a first material and a second longitudinal section is formed of a second material. The material of the second longitudinal section is more flexible and/or has a higher resilience than the material of the first longitudinal section. A described method for producing the fluid line relates to an adaptive attachment of the heat conductor on the outside of the pipeline that permits the heat conductor to be wound around fluid coupling and/or connector parts, in particular the housings by means of which the line is assembled, without strand separation.
