By using energy minimization computations we study the distortion of a wetting contact line pinned on a single defect. We find that the elastic restoring force of the line depends non-linearly on the amplitude of the distortion and we estimate the anharmonic corrections to the linear elastic model. These results suggest the importance of non-linear effects in the problem of contact line pinning.
