Abstract: A cord clamp for binding flexible cords and the like having a sleeve and plunger which are axially movable with respect to one another. One end of each of the plunger and sleeve is provided with a shoulder to prevent separation as the pieces undergo axial movement, and a channel and rib are provided to prevent relative rotation of the plunger and sleeve. The plunger and sleeve are each provided with alignable openings in offset relation to the rib and channel assembly, and these openings move into and out of radial alignment as the plunger and sleeve are axially moved with respect to one another. A spring is provided to urge separation of the plunger and sleeve so that the openings are biased to be out of radial alignment. A cap member seals the entire structure at an end opposite the shoulder formed on the sleeve.
