A securing mechanism for blind fascia is provided. The mechanism includes a removable fascia connector that is movable between an engaged position that effects the securing of the fascia and a disengaged position that allows the fascia to be removed, which includes a removable fascia connector that can be used to attach the fascia to the end plate. The fascia connector includes a first securing counterpart that is elongated, a second securing counterpart, and a stem, which has an elongated cross-section, that connects the first securing counterpart and the second securing counterpart such that the first securing counterpart, the stem, and the second securing counterpart form a unitary structure, and the first securing counterpart, die stem and the second securing counterpart rotate together; and a handle operatively connected to the stem. The end plate includes a third securing counterpart, which includes a receptacle and an opening to the receptacle, the opening allows the stem to pass through in to the receptacle and the receptacle blocks the movement of the first or the second securing counterpart therethrough.

A winder device is provided for winding or unwinding a chain or cord of a blind assembly. The device includes a first base, on which two shaft counterparts are disposed. The device also includes a second base, on which two shaft counterparts a disposed. The shaft counterparts on the first base and the shaft counterparts on the second base cooperate to form two shafts. One of the shafts is disposed in an end loop of the chain. The chain is disposed to a side of the other shaft such that the movement of the chain about the one of the shafts is restricted. The winder device further includes a stopper that limits a movement of the chain about the shafts when the stopper is connected to the first and the second base.
