ABSTRACT:
A facial shield assembly for use by dental and medical personnel comprises a transparent plastic shield having a substantially flat front portion and a peripheral border portion extending continuously around the front portion to cover and embrace at least part of a wearer's face. Concave groove structures are provided at the sides of the peripheral border portion to receive a U-shaped band. The groove structures are held on the band by clips which embrace the groove structure. The groove structure and clips have converging walls so that the clip can be wedged onto the groove structures to hold them onto the support band.
