An intermediate element for a medical extracorporeal fluid line designed to conduct a fluid, such as blood, has a main part extending between two connection parts. A flow channel passes continuously through the main part and the connection parts. The connection parts hydraulically connect the main body to a fluid line. On the periphery of the main part a receiving area is arranged, which is designed to receive a measurement value transmitter. An opening to the flow channel is defined in the receiving area and is sealed in a fluid-tight manner towards the receiving area by an elastic element. The measurement value transmitter is a gas sensor of a sensor device for measuring at least one gas contained in the fluid. The elastic element is a diffusion element, which is permeable to at least one gas. The diffusion element is bonded to an edge of the opening.
