A non-screwed fastening device has a retaining ring and a shaft lever. The retaining ring has a first annular edge, an inner ring flange and a second annular edge. The first annular edge has a plurality of slits to make the retaining ring resilient and at least a groove located in the inner surface of the retaining ring. The inner ring flange is disposed in the surface region of the retaining ring for buckling the retaining ring and the shaft lever, and the second annular edge further has a recess region. The shaft lever has a first circular flute, a second circular flute, a first end portion and a second end portion. The first circular flute and the second circular flute are selectively buckled to the inner ring flange by the retaining ring resilience. One side region of the shaft lever having at least a lug is placed into the retaining ring along the groove and the first end portion is put into the locating hole of the peripheral device such that the lug is locked to the recess region for fastening.
