A fastening means for attachment to a sheet material, the fastening means comprising a body (20) for location on one side of the sheet material, at least one blade member (23,24) resiliently attached to the body (20) and being movable relative thereto to define a gap for reception of the sheet material, the at least one blade member (23,24) being adapted for insertion through a similarly shaped aperture (A) formed in the sheet material so that on rotation of the body (20) sheet material adjacent said aperture (A) enters said gap and is used by the blade member(s) (23,24) into contact with the body (20) to thereby secure the fastening means to the sheet material. |
