摘要:
A novel device for fastening perforated cylindrical sleeves to handles of radial hairbrushes, consisting of a hole formed in the head of the handle carrying the radial brush and coincides, in position and shape, with a second hole formed in the vicinity of the lower opening of the circular sleeve with perforated walls which is fitted on the head of the handle for holding the brush and, when both holes are in coinciding positions, the blunt tip of the body of the resilient fastening element is fitted with pressure in the holes, the fastening element having a 90° peripheral projection which forms a step and the wall of the rim of which is extended in an inclined manner towards the tip of the fastening element, the edges of the holes being gripped with pressure between the step referred to and a second step existing in the same body, the two steps being spaced apart.
