A vehicle mirror assembly has a mirror retention plate having two parallel free edges and a replaceable mirror plate having a first surface to which the mirror is attached and a second surface opposite said first surface. The second surface has two parallel edges which includes projections on one of said edges able to retain one of said edges of the retention plate. On the second edge of said second surface of the mirror plate is a releasable locking mechanisms engageable with the other of said free edges of the retention plate. This allows the mirror plate to be simply snapped into position and released by triggering the release mechanism.
