Abstract: A centering interface is arranged between a tubular element mounted in a device, specifically a receiving tube or quiver, for a suction rod of a dialysis machine, and a movable element preferably guided pivotally about an axis, specifically a front plate of the dialysis machine. Centering surfaces are mated between the tubular element mounted in the device and the movable element. When a preferably sealed joint of the interface is manufactured, the tubular element mounted in the device can be moved in the axial direction against the force of a biasing spring during the movement of the movable element and the accompanying approach of the centering surfaces, while its guiding support allows a movement that permits the centering surfaces to be brought into the joining position with centering surface axes aligned with each other free of constraint forces.
