The shelf support is of the type which extends along the whole of the rear of a glass shelf. The shelf is inserted in a slot formed between a support member and a retaining member so that the shelf is retained as a cantilever. The retaining member carries an elastically-deformable strip which has a main part and spaced protuberances along its bottom. The retaining member is also of special construction, being of generally triangular shape with a slot in its bottom for receiving an upwards projection on the strip and holding the strip in position along the underside of the retaining member.
