Abstract
A draw-cord assembly comprises a draw-out which is extensible from a retracted condition to an extended condition and restraining means, secured in the cord. The cord and restraining means are such that the cord is retained in its retracted condition by the restraining means until the means is rendered ineffective, whereupon the cord is permanently extended from its retracted condition. The restraining means retain the cord in its retracted condition provided that the lengthwise load exceeding a certain minimum load is not exceeded, but extended by application of a greater load.
