The securing section comprises a plurality of rounded tips arranged at even radial distances from said longitudinal axis, at angular intervals between each other, each rounded tip having a pair of lateral flanks extending from a common apex toward an intermediate section connecting lateral flanks of a pair of adjacent rounded tips. Preferably the receiving opening comprises a number of rounded tips which is twice the number of rounded tips provided on the raised section.
