A showcase having a rectangular frame closed at the back and a slidably insertable and removable transparent front frame. One side and the top and bottom pieces of the frame have grooves for slidably receiving the front pane along its corresponding edges. The other side piece has a longitudinal side-to-side opening through which the front pane is slidably inserted and removed, and a front-to-back recess which intersects the opening. A retainer pin is removably positioned in this recess to hold the front pane in place.
