  • the internal diameter of the base 9 ', over most of it in height, is significantly greater than the outside diameter of the shirt 14.
  • the base 9 ' has, at its upper end, a collar 49 of reduced outer diameter and whose inner diameter is equal, at operating clearance, to the outside diameter of the jacket 14.
  • the superimposed discs 8 have a sufficient diameter to support against the inner surface of the large diameter part of the base 9 ', so that the discs 8 cannot pass through the neck 49.
  • the base 9 ' has a removable bottom 50, constituted by a disc provided, on its periphery, latching means 51 suitable for cooperate with combined means 52, for example a rib circular, provided on the internal wall of the base 9 '.
  • the user can release the bottom 50, from the base 9 ', and remove the element worn by sliding down. A refill is then put in place, by sliding from bottom to top; the bottom 50 is then fixed, by latching, in the base 9 '.
