A device for the application of a cosmetic and/or skin care product, includes an applicator element adapted for the application of the product. According to a preferred example, the device includes a first member having an aperture through which the applicator element extends, with a first part of the applicator element presenting an application surface projecting beyond a first side of the aperture. In addition, a second member forms a recess designed to receive therein a second part of the applicator element projecting beyond a second side of the aperture, with this second side being opposite the first side. The first member is connected to the second member by a hinge designed to pivot about an axis (Y) so as to allow the first member to move relative to the second member between a first position in which the second part is immobilized or held between the two members and a second position in which the applicator element is detachable.
