ABSTRACT:
A coupling for fluidly connecting flexible tubing includes a rigid connector and an elastic retaining sleeve. The rigid connector has a main portion and a first and preferably second male end portions projecting therefrom with a fluid passage disposed within the male end portions and the main portion for fluid communication with the flexible tubing. The elastic sleeve member has a connector gripping section that circumferentially grips the main portion of the connector and a first and preferably second section for gripping the flexible tubing. The first and second sections are initially in a retracted position, folded-back over the connector gripping section and are movable to a second tubing-engaging position to grip the tubing. Preferably, handles are attached to the first and second gripping sections of the sleeve proximate their ends so that the sleeve may be gripped manually to facilitate movement of the first and second sections from the retracted position to the tubing-engaging position.
