Claim:
A mirror support plate having an upper and a lower edge for use with right and left sides of vehicles which is slidable and engagable with a holder by means of a chucking and sliding connection comprising: said mirror support plate having two substantially parallel ridges which protrude from its back, said ridges each having at least one inwardly directed projection providing engaging surfaces which frictionally engage with a border region of the holder when said holder is inserted between the back and the projections; said mirror support plate being provided with a first elastic element and a second elastic element arranged in longitudinally spaced positions and which are each operative to function as a lower and an upper elastic element depending upon the position of said upper and lower edges when attached with said holder, wherein; during insertion of the mirror support plate from said upper edge only said first of said elastic elements is biased elastically towards the back of the mirror support plate to spring back into interlocking contact with said holder when said holder is fully seated with said support plate and during insertion of the mirror support plate from said lower edge only said second of said elastic elements is biased elastically towards the back of the mirror support plate to spring back into interlocking contact with said holder when said holder is fully seated with said support plate.
