An improved snap-in connector incorporating a liner or insert for the outbound end of the snap-in connector that comprises a generally cylindrical body having an outer periphery and inbound and outbound ends is described. The insert includes at least two, preferably three and most preferably four tabs that extend outwardly from the outer periphery of the inbound end and engage cast-in recesses in the inner periphery the outbound end of the snap-in connector. Also extending outwardly from the outer periphery of the liner or insert at points between the inbound and outbound ends of the liner or insert, and radially offset from the first set of tabs, is a second set of tabs, and preferably four in number that engage the outermost outbound end surface of the snap-in connector. Each of the tabs of the second set of tabs has an inbound surface that faces and lies parallel to the first set of tabs and an outbound surface that faces away from the first set of tabs and is angled so as to facilitate insertion of the liner into the outbound end of the snap-in connector from inside of the snap-in connector. The location of the second set of tabs is such that the distance between the first set of tabs and the second set of tabs is approximately the same as the distance between the recesses in the inner periphery of the outbound end of the snap-in connector that engage the first set of tabs and the surface of the outbound end of the snap-in connector that engages the second set of tabs.
