gag harness
A gag secured in place using more elaborate sets of straps than the normal two side straps.
Usually there are two straps that start at the sides, pass over the cheeks (forming a triangular shape), rejoin above the nose, from which a strap runs centrally across the face and turns over the head. However, there are also versions without the center strap. Some versions are one with the blindfold.
