Patent ID: 8196968

Claim:
A pipe connection assembly, comprising: an elastomeric sleeve having a peripheral, radially outwardly protruding stop formed thereon, the stop having a circumferential length that defines a sinusoidal-shaped path configured for engaging an aperture in a pipe wall; and a generally cylindrical rigid hub having an outer surface, one end of the hub having an outer diameter larger than an inner diameter of the sleeve but configured to fit inside of the sleeve by compression fit; wherein the hub has a rigid shoulder projecting radially outwardly from the outer surface of the hub, such that the shoulder abuts an inner surface of the sleeve adjacent to the peripheral stop and conforms to the sinusoidal shaped path of the peripheral stop, when the hub is inserted into the sleeve; wherein the sleeve and hub are assembled with the shoulder inside of the sleeve so that the shoulder on the hub is adjacent to the stop on the sleeve; and wherein a pair of diametrically opposed bosses protrude outwardly from the shoulder.
