Abstract: A device for removing callouses, especially in chiropody, is provided. A functional element is exchangeably arranged on a handle. To make mounting easy and safe, the functional element can be clamped between a front mounting segment of the handle and a fastening element that is articulated on the mounting segment. In a first position, the fastening element is pivotable about a pivot axis that runs perpendicular to the longitudinal direction of the handle. In a second position, the fastening element is displaceable relative to the handle via guides provided on the mounting segment. The fastening element can be fixed in a positive manner to the mounting segment by being displaced in the direction toward a rear handling segment of the handle.
