1. A spherical plain bearing for a ball-and-socket joint, comprising: two plain bearing shells, each plain bearing shell comprising a sliding layer containing a sliding material, at least one elastic layer, a stable support layer arranged between the sliding layer and the elastic layer, the stable support layer comprising a metallic material, and a further support layer provided on a side of the elastic layer which is remote from the support layer, wherein each of the two plain bearing shells have an annular, radially outwardly pointing flange, wherein the sliding layer is bonded to the support layer by an adhesive layer, the adhesive layer comprising a fluoropolymer. 2. The spherical plain bearing of claim 1, wherein the elastic layer in the plain bearing shell is prestressed substantially perpendicularly to the layer extent. 3. The spherical plain bearing of claim 1, wherein the elastic layer is bonded to the support layer and the further support layer via an adhesion promoter layer. 4. The spherical plain bearing of claim 1, wherein the elastic layer contains an elastomer. 5. The spherical plain bearing of claim 1, wherein the sliding material includes a plastic. 6. The spherical plain bearing of claim 5, wherein the plastic includes a high-temperature plastic. 7. The spherical plain bearing of claim 1, wherein the sliding layer contains lubricants and/or fillers. 8. The spherical plain bearing of claim 1, wherein the thickness of the elastic layer is from about 0.1 to 1.0 mm. 9. The spherical plain bearing of claim 1, wherein the thickness of the sliding layer is from 0.05 to 1.0 mm. 10. The spherical plain bearing of claim 1, wherein the thickness of the stable support layer is from 0.2 mm to 1.0 mm. 11.
