  • the groove 33 develops transversally to the sagittal plane 1 c. Therefore, the groove 33 develops on two opposite sides of the profile 3 with respect to the sagittal plane 1 c. Furthermore, even more in detail, preferably the groove 33 develops symmetrically with respect to the central axis 1 a.
  • the groove 33 could also develop along the sagittal plane 1 c.

  • the gripping elements 40a protrude from the bottom wall 4 alongside part of the side walls 2.
  • the gripping elements 40a may be defined by walls and the connector 40 may substantially correspond to a cavity, for example a through cavity starting from the profile 3 and ending at the end wall 4, as further specified below.
  • the socket elements 40a are configured to retain a spherical magnet 11 .
  • the gripping elements 40a define gripping surfaces 40b.
  • the gripping surfaces 40b are mutually facing each other and define concavities in the shape of a spherical cap to house in a compliant way part of the spherical magnet 11 .

  • the gripping elements 40a are preferably arms between which the spherical magnet 11 is to be inserted, the gripping elements 40a may be flexible in such a way as to allow the spherical magnet 11 to be housed in a compliant way by interlocking. In other words, the spherical magnet 11 can be pushed between the gripping elements 40a which flex elastically to accommodate the spherical magnet 11 and return into position.

Therefore, it may be contemplated, in the production phase of the component 1 , to insert the spherical magnet 11 between the rigid gripping elements 40a and then to lock the spherical magnet 11 into the connector 40 by constraining the lid, for example by gluing and/or welding and/or interlocking, to the ends of the gripping elements 40a.
  • the bottom wall 4 and the profile 3 may, being mutually independent although connected by the side walls 2, define different shapes and dimensions.

In this case, the through cavity substantially ends at the respective second opening 41. Furthermore, in this case, if the component 1 is realised according to the second embodiment form, there is no need for the gripping elements 40a to define gripping surfaces 40b.
