A splash guard device for sink, comprising a support frame (9, 11) for mounting the splash guard device on an upper edge of a sink, and a covering hood connected to the support frame, wherein the covering hood and the support frame define an access opening through which a user can reach into the sink from the user side, wherein the covering hood, when the splash guard device is mounted on a sink, partially covers a sink opening of the sink, wherein the support frame and the covering hood are arranged in such a way that when the splash guard device is mounted on a sink, the covering hood covers a partial area of the sink opening adjoining the rear wall of the sink facing away from the user side of the sink, and wherein the covering hood has a free edge extending between two ends of the connecting region between the support frame and the covering hood, and wherein the free edge is curved and approaches the rear edge of the covering hood at least in sections starting from the ends of two lateral outer edges (15, 16) of the covering hood, wherein the free edge at the same distance from the ends of the two lateral outer edges (15, 16) of the covering hood has the smallest distance to the rear edge of the covering hood, and wherein the covering hood is concave in shape, with the concave curvature facing the opening of the sink when the splash guard device is mounted, characterized in that the support frame comprises a retaining web which is intended to fix the support frame on an upper edge of a sink in a form-fitting manner in the lateral direction, wherein the retaining web of the support frame protrudes from the covering hood, and wherein the covering hood projects beyond the retaining web on its outwardly facing outer edge, such that the section of the covering hood projecting beyond the retaining web rests on an upper side of the sink when in use, and wherein the section of the covering hood projecting beyond the retaining web forms the support frame as a projection together with the retaining web. a support frame (9, 11) for mounting the splash guard device on an upper edge of a sink, and a covering hood connected to the support frame, wherein the covering hood and the support frame define an access opening through which a user can reach into the sink from the user side, wherein the covering hood, when the splash guard device is mounted on a sink, partially covers a sink opening of the sink, wherein the support frame and the covering hood are arranged in such a way that when the splash guard device is mounted on a sink, the covering hood covers a partial area of the sink opening adjoining the rear wall of the sink facing away from the user side of the sink, and wherein the covering hood has a free edge extending between two ends of the connecting region between the support frame and the covering hood, and wherein the free edge is curved and approaches the rear edge of the covering hood at least in sections starting from the ends of two lateral outer edges (15, 16) of the covering hood, wherein the free edge at the same distance from the ends of the two lateral outer edges (15, 16) of the covering hood has the smallest distance to the rear edge of the covering hood, and wherein the covering hood is concave in shape, with the concave curvature facing the opening of the sink when the splash guard device is mounted, characterized in that the support frame comprises a retaining web which is intended to fix the support frame on an upper edge of a sink in a form-fitting manner in the lateral direction, wherein the retaining web of the support frame protrudes from the covering hood, and wherein the covering hood projects beyond the retaining web on its outwardly facing outer edge, such that the section of the covering hood projecting beyond the retaining web rests on an upper side of the sink when in use, and wherein the section of the covering hood projecting beyond the retaining web forms the support frame as a projection together with the retaining web.
