Cleché
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). 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.
