A cord lock of unitary construction comprising a body of resilient material and a slit through the center thereof that defines two cord gripping surfaces. A cord or cords threaded through the slit are securely engaged by a clamping effect at the slit and surface friction between the cords and the gripping surfaces of the slit. The clamping effect results from pressure being applied to the base of the cord lock by the article to which the cords are attached. One releases the cords by squeezing with the fingers the exterior sides of the cord lock body, which are perpendicular to the slit. This causes the slit to pucker and thus spread the slit walls. A hollow section in the base of the body allows the slit to open and release the cords when pressure is applied with the fingers to the base of the cord lock. The gripping surfaces of the slit can be modified to improve their cord-gripping or durability properties to meet specific cord-locking applications. The exterior surface can be molded into any shape or color to meet certain cord locking applications and/or visual market appeal. |
