The present invention relates to a hook-shaped arrangement (1) which comprises a main part (1a), a hook-shaped device (1b) integral with said main part, and a holding means (2) which is integral with or attached to said main part. The hook-shaped device (1b) is comprised of a tongue (5) which is part-circular, or at least essentially part-circular in cross section and has an angle of arc slightly below 360°. The center (5') of the curved tongue is located in a plane (A) which coincides with a plane (A') that lies on one side surface (7) of the main part. The free end (5a) of the tongue extends in a plane (B) that coincides with a plane (B') lying on that side surface (8) of the main part opposite to said one side surface (7) of said main part.
