A fan base comprising an inner base and an outer detachable base, the inner base of which is slideably engageable into the track of the outer detachable base. The inner base has engagement rails on either side thereof which slide into and engage with engagement slots in the ends of the detachable base. The detachable base also has a retainer, which is a piece separated from, and slightly inclined with respect to, the track of the detachable base.
