Abstract: An improved safe structure of cord set for a window curtain includes a base, a plurality of towing cords, a shade body and a pulling cord unit. The shade body is provided for each towing cord with buckles and a connector for connecting an end of the towing cord. The connector includes a socket fixed on the shade body, an insertion connecting member connected with the socket for fixing an end of the towing cords, the insertion connecting member has a blind hole for placing therein an end segment of the towing cords, thereby blocking of the end segment in the buckle is prevented when the connecting member is released from the socket, the buckle has thereon a breaking slit, thereby the towing cord can be loosened and released from the buckle when it is exerted with an axial pulling force over a predetermined value.
