Method for producing a cage nut having a retaining device

Method for producing a cage nut (1), wherein the method comprises the assembly steps of:

• punching out a bracket-shaped holder (7) comprising a base plate (30) and three angled legs (27, 28, 29), and a passage opening (8) having an insertion slot (13) in the base plate (30);
• producing a nut (4) comprising a radially protruding angular flange (5) and a threaded-sleeve-like receptacle (6) for bolts;
• injection moulding a retaining collar (9) comprising cover elements (10, 11) for covering the passage opening (8) of the holder (7) on both sides of the passage opening, and comprising a connecting bush (12) which connects to the cover elements (10, 11);
• putting the retaining collar (9) onto the base plate (30) of the holder (7) via the insertion slot (13) until the cover elements (10, 11) cover edge regions of the passage opening (8) on both sides;
• axially displacing the threaded-sleeve-like bolt receptacle (6) of the nut (4) into the connecting bush (12) of the retaining collar (9) in the passage opening (8);
• and
• caulking an end of the threaded-sleeve-like bolt receptacle (6), which end projects from the retaining collar (9), to an axially oriented cage nut (1) which is radially displaceable in the passage opening (8).
