A device for fixing a camera to a tripod which comprises a base and a slider to which a camera is to be fitted. Both base and slider are prepared from synthetic resin. The slider is slidably fitted on the base. One of the slider and base is provided with a projection, and the other thereof is provided with an integral elastically deformable piece. This deformable piece involves a protrusion engageable with the above-mentioned projection when the slider is set on the base, and a free end which allows for the elastic deformation to remove the slide from the base.
