A securing device for securing a connecting arm to a ceiling fan blade. The blade includes a hole through which a male member of the arm is inserted. The securing device includes a plate having an aperture through which the engagement end subsequently extends with the neck staying within the aperture. The aperture includes a smaller part having a rim portion such that the plate is slidable in a first direction along the blade surface until the rim portion engages behind the engagement end. The rim portion is enlarged for receiving and engaging with the engagement end in a second direction opposite to the first direction. The plate includes a resilient finger deformable upon engaging the blade surface, resiliently maintaining the engagement of the enlarged rim portion with the engagement end in the second direction. The finger engages the blade surface by friction, thereby holding the plate against sliding relative to the blade in the second direction.
