Abstract
A cord locking device of this invention comprises a casing having openings respectively at opposite ends and a longitudinal aperture in a front plate, and a slide adapted to be inserted in the casing. The slide has a pair of resilient grip portions extending from opposite sides of a head portion of the slide, and also has a pair of engaging portions each extending from a side surface of the slide between the head portion and a base of each of the grip portions. In order to increase the resilience, the slide further has a resilient portion situated between the grip portions. The slide additionally has a central resilient guide portion situated rearwardly of the head portion in such a manner that the guide portion should project outwardly from an outer surface of the front plate of the casing through the aperture when the slide is inserted in the casing. For locking and unlocking the cord, the slide is slided with the gripping of the grip portions. When the guide portion is depressed in the aperture, the slide can be removed from the casing for exchanging the cord with a new one.
