Abstract: A frictional cord lock for use in locking one portion of a single length of cord relative to another. A first embodiment includes a cylindrical, barrel-shaped member having a cylindrical wall substantially surrounding a longitudinal axis, has a first cord end fixed in one opening in the cord lock. Second and third tear-drop shaped openings lie along a common axis that forms an angle with the longitudinal axis and receive a second portion of the cord, the first opening lying vertically between said the second and third openings. The cord slides freely in second and third openings when pulled along their common axis but locks when subjected to non-axial forces. The non-axial forces pull the cord into the v-shaped portion of the openings pinching the cord and securing them in place. A second embodiment employs a generally horizontal v-shaped channel to lock the cord in place.
