ABSTRACT:
An assembly for securing an apparatus to a facemask includes a U-shaped frame extending along similarly shaped portions of the facemask. Removable attachment clips secure the frame to the facemask. Two cylindrical pins with circumferential radiused grooves are attached to and extend from the top portion of the frame. The pins mate with bores in a clevis assembly, to which the apparatus can be attached. A spring-loaded bar spans between the bores. The bores in the clevis assembly receive the pins and the spring-bias causes the bar to engage with the grooves to secure the clevis assembly to the frame. A lever is rotatably attached to the clevis assembly. Pivoting the lever works against the spring-bias to lift the bar out of the grooves, disengaging the pins, and allowing the clevis assembly to be disengaged from the frame and facemask.
