摘要：
A polymer pipe includes a length between a first end and a second end, the length and the first end having a first diameter. The second end is a belled or female end having a second diameter larger than the first diameter. An insert device is received within the second end and has an annular body formed of a body material and has a spline portion formed as a part of the insert device. The spline portion includes a spline carried by the insert device and resiliently movable in a radial direction relative to an axis of the annular body.
