A brake manipulating member or operating member has a pair of opposed walls each formed with a hole. A capped bush made of abrasion-resistant synthetic resin and having a flange around a closed end thereof and a retaining flange around an open end thereof is fitted in the hole with the open end positioned inward. A rollershaped connector has a trunk portion slightly smaller than the hole in diameter, a short pin portion projecting from each end of the trunk portion, a wire engaging portion at the center of the trunk portion and an overall length equal to or slightly smaller than the outside width of the portion of the manipulating or operating member having the two walls. The opposite pin portions of the connector are inserted in and supported by the bushes mounted on the pair of walls.
