The settings are adapted so as to be fixable, in a removable manner, on any support of the plurality of supports by means of male and female coupling elements. The female coupling element is located inside the settings. Each support and/or each setting is provided with a blocking lever inhibiting a relative movement between the setting and the support on which the setting is fixed.
