A fluid product distributor, comprising:

• a reservoir for fluid product comprising a neck;
• a pump;
• and
• a fastening system connected to the neck, the fastening system comprising:
• a fastening ring comprising a skirt engaged around the neck, the skirt comprising articulated fastening tabs and fixed tabs;
• a rigid collar engaged around the skirt so as to fold back the articulated fastening tabs to frictionally engage the fixed tabs.

A fastening system, comprising:

• a fastening ring, comprising:
• an annular plateau;
• an upper portion extending away from the annular plateau in a first direction;
• a skirt extending away from the annular plateau in a second direction opposite the first direction, the skirt comprising:
• at least one articulated tab comprising a thread on an internal surface of the at least one articulated tab;
• and
• at least one fixed tab, each of the at least one fixed tabs comprising:
• a pair of opposite lateral edges;
• an axial rib running along each of the pair of lateral edges and extending radially inward;
