Alternatively, the mounting bracket 18 and the support plate 12 are arranged as an integral unit, for example as a single moulded unit, wherein the mounting bracket is formed in the support plate. The support plate 12, or at least the back side 19 thereof, extends in a plane substantially along the longitudinal axis A. For example, the support plate 12 is substantially rectangular or square, optionally with rounded corners. Alternatively, the support plate 12 is oval or circular.

[0025] The back side 19 of the support plate 12 is provided with one or more fastening devices 20 comprising a permanent magnet 21 and a friction-increasing material 22 for fastening the support plate 12 to the surface of a vertical element 23 by magnetism in combination with friction, so that the earplug dispensing system 10 is attached to the vertical element 23 by means of the fastening devices 20. The fastening devices 20 are illustrated with reference to FIGS. 2 and 3 and fastening to the vertical element 23 is illustrated in FIG. 5. For example, the earplug dispensing system 10 is attached to the vertical element 23 by means of the fastening devices 20 alone. In the illustrated embodiment, four fastening devices 20 are attached to the support plate 12, wherein the fastening devices 20 are distributed over the surface of the back side. For example, fastening devices 20 are arranged near corners of the support plate 12. Alternatively, any suitable size and number of fastening devices 20 are arranged on the back side 19 of the support plate 12 to attach the earplug dispensing system to the vertical surface by means of magnetic forces and friction. For example, the fastening devices 20 are attached to the support plate 12 by means of screws arranged through holes in the fastening devices 20. Alternatively, the fastening devices 20 are attached to the support plate 12 by means of an adhesive or other suitable fastening means. Alternatively, the support plate 12 comprises a magnetic material, such as iron, wherein the fastening devices 20 are attached to the support plate 12 by means of magnetism through the permanent magnet of the fastening devices 20. For example, the permanent magnets 21 are arranged with a front side and a back side, wherein the front and back sides are substantially plane and level and are arranged substantially in parallel. For example, the permanent magnets 21 are plate shaped. In the illustrated embodiment, the permanent magnets 21 are circular. Alternatively, the permanent magnets 21 are of any suitable shape, such as rectangular, oval, square, etc. The permanent magnets 21 comprises a ferromagnetic material, such as iron, cobalt, nickel, neodymium or other metals, alloys or minerals that can be magnetized to produce a magnetic field for attachment to the vertical element 23 by magnetic forces. At least the back side of the permanent magnet 21 is provided with the friction-increasing material 22, wherein the friction-increasing material 22 is arranged for engaging the surface of the vertical element 23 and preventing the earplug dispensing system 10 from displacement in a plane of the vertical element 23.
