A cup (100) has at least one retaining element (50) for securing said cup (100) to an end coil (40) of a helical spring, said cup (100) comprising a ramp (10) for supporting said coil (40) and a centring surface (13) for centring said end coil (40). The retaining element (50) is deformable such that the coil (40) has at least one surface for permanent contact both with the retaining element (50) and with the ramp (10) for variable diameters of the end coil (40). |
