A rearview device attachment assembly includes a mount having a periphery that defines first and second recesses. The mount is configured to engage a windscreen button. An attachment clip is coupled to the mount at a central portion of the attachment clip. The attachment clip includes first and second opposing loading members that abut the first and second recesses. A flex portion extends from each of the first and second opposing loading members. A connection portion extends inwardly from each flex portion. Each of the first and second loading members of the attachment clip is pre-loaded during coupling of the attachment clip to the mount, but prior to rotational engagement of the attachment clip with engagement surfaces of the windscreen button.
