Abstract

In combination, a syringe tip and a fitting for releasably connecting the tip to a hand piece for delivering a fluid forward to a mouth of a patient. The hand piece has a passageway for delivering the fluid to a discharge end of the hand piece. The syringe tip includes an elongate tube having an exterior surface and an interior passage extending through the tube for transporting the fluid to the patient, the exterior surface of the tip including a portion having a generally constant size and uniform shape. The fitting includes a body adapted to attach to the hand piece adjacent the discharge end, the body having a central opening sized and shaped for receiving the portion of the tip. The fitting also includes a gripping mechanism mounted in the opening having a plurality of locking fingers disposed around the opening. Each of the plurality of fingers includes a tooth extending inwardly into the opening and having a rearward facing point adapted to releasably engage the portion of the exterior surface of the tip when the tip is received in the opening and to prevent ejection of the tip from the opening due to forces applied to the tip by the fluid being transported through the tube to the patient, thereby to secure the tip to the hand piece when the teeth engage the portion of the tip.
