A cord retainer comprising an outer tube, a slide, and a plug. The slide has a cord insertion hole and a pair of legs. The outer tube has a pair of horizontal cord insertion holes and in its inside surface a number of guide grooves; some guide grooves have each an aligning engagement portion while the remaining guide grooves have each a holding engagement portion. The plug has a number of locking strips, some of which have each at its upper end an aligning projection and at its base a holding projection while the remaining locking strips have each at its upper end a holding projection. The plug further has a cam surface as an inside surface an insertion portion. In use, the plug is inserted into the tube from the lower end until each aligning projection comes into engagement with the respective aligning engagement portion, and the slide is inserted into the tube from the upper end until the hole of slide is aligned with the holes of the tube, facilitating threading a cord through the slide and the tube. With the cord inserted, if the plug is pushed up into the tube to be completely assembled, the legs come into contact with the cam surface to resiliently urge the slide upwardly to retain the cord. For adjusting the cord, the slide is pressed down.
