Cage nut having a retaining device and method for producing same

A cage nut including a retaining device, said cage nut comprising:

• a nut (4) comprising a radially protruding angular flange (5) and a receptacle (6) for a bolt;
• a holder (7) having a passage opening (8), through which the bolt receptacle (6) passes, the holder (7) being engagable over the angular flange (5);
• and
• a retaining collar (9), which surrounds the bolt receptacle (6) of the nut (4) and is supported on the holder (7) in the region of the passage opening (8);
• wherein the retaining collar (9) is in one piece and comprises first and second cover elements (10, 11) cover the passage opening (8) of the holder (7) on both sides of the passage opening, and wherein the cover elements (10, 11) are mechanically connected via a connecting bush (12) which concentrically adjoins the bolt receptacle (6), and wherein the connecting bush (12) is radially spaced apart from the passage opening (8);
• and
• wherein the first cover element (10) is a plate which comprises resiliently pretensioned wave-shaped indentations (25) or bulges (24) at edges (22, 23) transverse to an insertion slot (13) relative to the holder (7).
