Abstract: Wheel guard for a two-wheeled vehicle comprising a device for detachably fastening the wheel guard proximate to the fork of the two-wheeled vehicle, in which the fastening device has at least one expansion element (10) that can be inserted into a tubular part (11) of the fork and clamped in place there, and at least one sliding element (12) that can be joined with the expansion element, wherein the sliding element can be inserted into a groove (13) or rail on the wheel guard (14), and detachably fixed in an end position. The object of this invention is to create a wheel guard for a two-wheeled vehicle with a device for detachably fastening the wheel guard proximate to the fork of the two-wheeled vehicle, in which the wheel guard can be disassembled or assembled easily without a tool, wherein the wheel guard fastening device is also suitable for two-wheeled vehicles with spring-mounted front wheel forks.
