Abstract: An anti-tangling coupling device has an inner portion which is rotatably engaged with an outer portion. Fluid containment devices such as hoses can be coupled at either end of the device. One hose is secured to the inner portion while a second hose is secured to the outer portion, with the hoses being positioned at opposite ends of each other. Fluid communication is maintained throughout the inner portion and the outer portion, allowing water to flow between hoses coupled with the device. The rotational engagement is achieved by a bearing assembly, the bearing assembly including an inner race, and outer race, and ball bearings secured in cages. The ball bearings are capable of rotational movement (imparted from contact with the first race and second race), but are prevented from translational movement by a cage. As a result the likelihood of tangling between coupled hoses is greatly reduced.

When the adapter component is slidably engaged with the port component the cutout section and the projecting tab engage to prevent sliding withdrawal of the adapter component from the port component. The flexible cam locking post also engages with the cutout section and prevents the adapter component from rotating.
