A connecting device is provided to connect a fan blade to a rotor of a motor of a ceiling fan. The connecting device includes a bottom member disposed transverse to and rotated about an axial direction of the rotor. A circumferential wall extends upwardly from a periphery of the bottom member. A mounting arm has an anchored end adapted for mounting the fan blade thereon, and an anchoring end disposed to be brought to anchor on the bottom member such that the mounting arm is oriented in a radial direction relative to the bottom member. A limiting unit is disposed between the anchoring end and the bottom member to limit further movement of the anchoring end relative to the bottom member once the anchoring end is pulled away from the bottom member. At the same time, a biasing member is disposed to bias the anchoring end to move away from the bottom member. By virtue of the limiting unit and the biasing member, the anchoring end can anchor on the bottom member steadily and conveniently.
