Mounting for a body coil of a magnetic resonance device is provided. A reversible and universal mounting device for a body coil in the magnetic resonance device is provided. The mounting device includes at least one expanding ring for creating a way of retaining the body coil in a tunnel-shaped magnetic opening of the magnetic resonance device. The mounting device also includes at least one expander that is configured to enable the expanding ring to be mounted on the inside of the tunnel-shaped magnetic opening of the magnetic resonance device by spreading. The mounting device includes at least one mounting element for mechanically supporting the body coil on the expanding ring.
