The utility model discloses a drawing-resistant connecting piece. The drawing-resistant connecting piece comprises a bolt, a nut and a tubular fastener, wherein the nut is in threaded fit with the bolt; a through hole through which a screw rod of the bolt penetrates is formed in the fastener; the size of the through hole is smaller than that of the head of the bolt; a first notch groove in clearance fit with the screw rod of the bolt is formed in one side of the upper part of the fastener, is communicated with the through hole and extends from the top end of the fastener to the middle of the fastener along the vertical direction; a second notch groove in clearance fit with the screw rod of the bolt is formed in one side of the lower part of the fastener; the opening direction of the second notch groove is opposite to that of the first notch groove; the second notch groove is communicated with the through hole and extends from the bottom end of the fastener to the middle of the fastener along the vertical direction; one end of the first notch groove, the through hole and one end of the second notch groove are sequentially communicated to form a communicated opening which penetrates along the transverse direction, and the ends of the first notch groove and the second notch groove are both positioned in the middle of the fastener; the screw rod of the bolt penetrates through the communicated opening. According to the drawing-resistant connecting piece, convenience in installation and connection can be achieved, and the drawing resistance can be improved.
