  • Patent number: 12150543
    Abstract: A brush including a support made of bamboo material having a plurality of cluster holes each accommodating one bristle cluster fixed in a cluster hole by a clip having a length l greater than the diameter D of the cluster hole to form clip projections on both longitudinal ends. The clips have at least two wedges on at least one side disposed one above the other in the direction of the vertical axis and widening upward, the upper ends of the wedges forming catch shoulders extending in the longitudinal direction of the clip, wherein a press-in end of the clip having a reduced width is formed at a lower end of the lower wedge.
