ABSTRACT:
A safe disengaging device for the pull cord of a blind includes a male support base and a female support base. The male support base is fixed on the upper frame of a blind and provided with a protruding clasping block having its upper side formed with an engage shoulder. The female support base has its lower end tied with a pull cord and its upper end extending upward to form an elastic member corresponding to the clasping block of the male support base and having its upper free end formed with an engage hook to be engaged on the engage shoulder. When the pull cord is drawn by an excessively great force, the elastic member will be disengaged from the engage block, and the female support base together with the pull cord will fall off, avoiding accidents caused by improper operation of the pull cord and elevating safety in use.
