Cleché should not be confused with Cliché.
In heraldry, a cross (or other ordinary) cleché (clechée, clechy) flares out at the ends before tapering back to a point, in a shape resembling the bow of an old-fashioned key (French clé).[1] An example is the Occitan cross or Cross of Toulouse in the coat of arms of the counts of Toulouse: Gules, a cross cléchée, pommetty and voided Or. Because this Occitan cross is also voided (hollow), some writers[2] have mistakenly taken the term cléché to be a synonym of voided or to include voiding as a defining feature.[3]
