Abstract
A cord lock apparatus (100) is disclosed comprising a base (120) having a converging channel (128), and an elastically flexible locking insert (140) that is retained by the base. The locking insert defines a loop including left and right legs (146) that are generally parallel to the sidewalls (124) of the channel, and receive a cord (102) therebetween. When the locking insert is undeformed, the cord is clampingly engaged between the insert legs and the base sidewalls. The user pulls upwardly on the loop to elastically deform the insert such that the legs rotate inwardly, releasing the cord. The insert may also slide longitudinally to a limited extent in the channel. Teeth (123, 143) may be provided on the locking insert and/or the base to more securely engage the cord.
