Abstract: A microphone-speaker is removably attached to an article of clothing by a device having a sheet of flat material provided with a plurality of openings spaced along a circular circumference of selected radius and center. When fastened to the microphone-speaker, the openings form depressions. A flat resilient spring is pivotally attached to the sheet of material at the center and extends at least as far as the depressions so that a projection on the spring can engage the depressions. A clip is pivotally mounted on the spring in the vicinity of the projection and extends along the spring toward the center to one end of the clip. Means are provided to urge the one end of the clip toward the plane of the flat material so that the one end can be pivoted away from the flat material to permit an article of clothing to be resiliently held between the one end and the microphone-speaker.
