A glassware forming machine baffle arm assembly that includes: a baffle arm having an aperture, and a baffle manifold having a segment extending through said aperture and permitting rotation of said baffle manifold with respect to said baffle arm, characterized in that said same baffle manifold is mounted on said baffle arm by: a threadless nut (210 or 310), and a bayonet connection between said threadless nut (210;310) and said baffle manifold segment, said threadless nut (210;310) and said bayonet connection comprising a quick-connect/disconnect arrangement mounting the baffle manifold on the baffle arm, wherein said baffle manifold segment includes a stud having a plurality of lugs, and said threadless nut (210;310) includes: translational retention lugs (254 or 354) circumferentially spaced apart, and positionable behind said stud lugs when said threadless nut (210;310) is coupled to said stud, and rotational retention lugs (256 or 356) circumferentially spaced apart and positioned adjacent to said translational retention lugs (254;354), and positionable adjacent to said stud lugs such that said rotational retention lugs (256;356) axially overlap said stud lugs, wherein said translational and rotational retention lugs (254,256;354,356) define seats to receive said stud lugs and define passages circumferentially between said seats to allow passage of said stud lugs, and wherein said rotational retention lugs (256;356) are axially movable with respect to said stud lugs, and are rotatably movable with respect to said stud lugs when said rotational retention lugs (256;356) have been axially moved with respect to said stud lugs so as to axially clear said stud lugs. a baffle arm having an aperture, and a baffle manifold having a segment extending through said aperture and permitting rotation of said baffle manifold with respect to said baffle arm, characterized in that said same baffle manifold is mounted on said baffle arm by: a threadless nut (210 or 310), and a bayonet connection between said threadless nut (210;310) and said baffle manifold segment, said threadless nut (210;310) and said bayonet connection comprising a

retention lugs (256;356) axially overlap said stud lugs, wherein said translational and rotational retention lugs (254,256;354,356) define seats to receive said stud lugs and define passages circumferentially between said seats to allow passage of said stud lugs, and wherein said rotational retention lugs (256;356) are axially movable with respect to said stud lugs, and are rotatably movable with respect to said stud lugs when said rotational retention lugs (256;356) have been axially moved with respect to said stud lugs so as to axially clear said stud lugs. a threadless nut (210 or 310), and a bayonet connection between said threadless nut (210;310) and said baffle manifold segment, said threadless nut (210;310) and said bayonet connection comprising a quick-connect/disconnect arrangement mounting the baffle manifold on the baffle arm, wherein said baffle manifold segment includes a stud having a plurality of lugs, and said threadless nut (210;310) includes: translational retention lugs (254 or 354) circumferentially spaced apart, and positionable behind said stud lugs when said threadless nut (210;310) is coupled to said stud, and rotational retention lugs (256 or 356) circumferentially spaced apart and positioned adjacent to said translational retention lugs (254;354), and positionable adjacent to said stud lugs such that said rotational retention lugs (256;356) axially overlap said stud lugs, wherein said translational and rotational retention lugs (254,256;354,356) define seats to receive said stud lugs and define passages circumferentially between said seats to allow passage of said stud lugs, and wherein said rotational retention lugs (256;356) are axially movable with respect to said stud lugs, and are rotatably movable with respect to said stud lugs when said rotational retention lugs (256;356) have been axially moved with respect to said stud lugs so as to axially clear said stud lugs. translational retention lugs (254 or 354) circumferentially spaced apart, and positionable behind said stud lugs when said threadless nut (210;310) is coupled to said stud, and rotational retention lugs (256 or 356) circumferentially spaced apart and positioned adjacent to said translational retention lugs (254;354), and positionable adjacent to said stud lugs such that said rotational retention lugs
