An expansion ring for expanding the size of an oven is disclosed. The expansion ring has a plurality of expansion ring segments which are connected together by one or more clips. The expansion ring segments have end portions which, when two segments are placed in end-to-end relation, form an engagement portion having first and second stops. The clip has a channel which engages the engagement portion so as to hold the expansion ring segments together and a finger projecting into the channel. According to this arrangement, the clip is slidable between a first position where the finger engages the first stop and a second position where the finger engages the second stop. In the first position, the expansion ring segments are locked together. In the second position, the segments may be separated, but the clip remains attached to one of the segments so that it will not be lost. An oven incorporating the expansion rings and clips of the present invention is also disclosed.
