Abstract: A pedicure spa tub sanitary apparatus and system includes a disposable spa tub basin liner and a disposable gas jet member that includes a quick-connect coupling for easy assembly and removal after each use. The spa tub basin liner is made from plastic and conforms to the shape of the spa tub. The disposable gas jet member is also preferably made from plastic or other rigid material and cooperates with a valved gas coupling member secured in the spa basin wall to provide a safe and sanitary air jetting function when the spa tub basin is filled with water, thereby reducing the risk of spreading infectious disease. During use, the disposable gas jet member may be disposed within a wall trough of the spa tub to protect the disposable gas jet member and quick-connect coupling from accidental breakage and/or disconnection.

Abstract: A device for releasably fastening two string portions together includes a hollow housing and a movable locking member disposed within the housing. The housing extends in a longitudinal direction and includes a midportion disposed between first and second longitudinal end portions. The openings for feeding the string portions into the housing are disposed on opposite lateral sides of the housing entirely within the midportion of the housing. In this way, when the device is used to fasten string portions in a movable environment (e.g. shoelaces), the tension force of the string portions in conjunction with the first and second longitudinal end portions of the device inhibit the device from “flip-flopping” or otherwise moving relative to its environment.
