A cord lock for adjusting the length of a cord used in clothes or bags, including: a main body for receiving the cord, including a bottom cover portion, an outer cover portion and an inner portion formed on the bottom cover portion, a control space portion formed between the outer cover portion and the inner portion, and an oval-shaped first receptor hole and an oval-shaped second receptor hole respectively formed through the outer cover portion and the inner portion for passing the cord; control means for adjusting the length of the cord, which had passed through the first receptor hole and the second receptor hole of the main body, including an upper cover portion provided with a plurality of protrusions, and a control portion protruded approximately perpendicularly from the end of the upper cover portion, received by the control space portion, and provided with a third receptor hole for passing the cord; connecting means produced integrally with the control means and the main body by injection molding for integrally connecting the control means and the main body, and provided with a fourth receptor hole for passing the cord; elastic means assembled with the connecting means to hold the cord, having passed through the first receptor hole and the second receptor hole of the main body, for applying an elastic force to the control means, and provided with a through hole, the outer circumference of which contacts a protuberance of the connecting means, so that the elastic means is firmly assembled with the connecting means; and decoration means for covering the outer surfaces of the control means and the connecting means to ornament the outer appearance of the cord lock, and including through holes, into which the protrusions formed on the surface of the upper cover portion of the control means are inserted by interference fit, and a fifth receptor hole, formed through a portion thereof covering the connecting means, which communicates with the fourth receptor hole of the connecting means. The cord lock includes the main body, the control means, and the connecting means, which are produced into one integral component by injection molding, thereby having decreased production costs and improved productivity. Further, the cord lock comprises decoration means, which serves to ornament the external appearance thereof, and is pressed by an one-touch manner so as to release the holding of the cord, thereby being capable of easily adjusting the length of the cord and increasing convenience in use.
