Abstract
A part for connecting a fluid line to an opening of a container comprised of thermoplastic material or for closing the opening of the container has a first component and a second component of thermoplastic material. The first component has a surface to be connected to the container by forming a welded heat fusion joint. The first component has an insufficient diffusion barrier capability relative to hydrocarbon fuel. Compared to the material of the first component, the material of the second component has higher diffusion barrier capability, reduced swelling capability relative hydrocarbon fuel, higher mechanical strength, and higher thermal shape stability. The first component encloses the second component at least up to an injection location remote from the connecting surface. The material of the second component is injected into the still formable core of the material of the first component via the injection location.
