We compute the elastic interaction between two identical conical inclusions in a spherical vesicle. We find it always repulsive and proportional to the square of the contact angle. At small angular separations it decays as , as in the case of planar membranes. After a crossover , where ψ is the inclusions' aperture, it decays as , yielding a much stronger force than in a flat membrane. Finally, a quadratic minimum around the anti-polar configuration is reached.
