Yes indeedy for rubber soprano or slim metal alto tenor pieces Dukoff make a white or clear plastic ligature with one screw on top.
For rubber alto and tenor Rippamonti makes a slide on clear napkin ring type ligature usually three sizes per order.
For a Rovner style ligature Consoli ligs and Bari moutpieces make a white strap ligature.
I think that is all but there could be more antique or vintage stuff laying around in somebodys box or store but i don't know.
