Abstract
The invention relates to a rotatable connection device for a driving part (1) to a driven part (2), wherein the driven part has a rotational play relative to the driving part. The driving part (1) exhibits at least two axial elastic dogs (3, 4) which end in radial teeth (5, 6) and cooperate with circular arcuate slots (8, 9) in the driven part (2), which exhibit enlarged regions (11, 13) for the passage of the radial teeth (5, 6), and with a securing part (14). This securing part (14) is provided with holes (15, 16) to receive the elastic dogs (3, 4), and a bendable strap (17, 18), which is present at each hole (15, 16), after being bent behind the dogs (3, 4), comes into abutment opposite the teeth (5, 6) at their ends. Any accidental disassembly is prevented by this means.
