ABSTRACT:
A separable coupling for plastic tubing comprising a pair of plastic collars sized to form a high strength bonded interference fit with the ends of plastic tubing. A pliant elastomeric sleeve encircles and bridges the two collars and includes ribs internesting with grooves formed encircling the exterior of the collars. Clamping bands assembled about the sleeve bridging the two collars separably interlock the components together in a fluid-tight manner.
