An hollow sphere, in accordance with the preferred embodiment of the invention, has a slot formed on a somewhat less than semicircular portion of the great circle that separates the sphere into two hemispheres. A shower curtain grommet support is spaced inwardly of said slot to engage a shower curtain grommet and support a portion of the curtain. A pair of diametrically aligned small circles in the plane of hemispherical separation enables the holder to move freely on a shower curtain rod.
