A connector for temporary scaffolding at an end of a lateral member, to be wedge-connected to a receiver around a strut, includes: a wedge body provided movably at the end of the lateral member upward and downward relative to the lateral member; a locking body including a claw formed such that, as a result of the wedge-body's moving downward, the claw could travel from initial to locking position with respect to the receiver; and a biasing body capable of pressing the locking body toward the wedge body, wherein the wedge body includes a shoulder protruding toward the locking body, the locking body includes an interfering portion protruding toward the wedge body, and when the claw is at the initial position, the shoulder is blocked by the interfering portion from moving upward, thereby preventing the wedge body from moving upward and the locking body from traveling toward the biasing body.
