A polymer pipe has a length between a first end and a second end. The length and the first end have a first diameter and the second end is a belled end having a second diameter larger than the first diameter. An insert device is received or pre-installed within the second end and has an annular body with a seal part coupled to the annular body and a spline groove formed in the annular body and facing radially inward. Another polymer pipe is inserted in the belled end to form a pipe joint assembly and has a mating spline groove on the outer surface. The spline groove and mating spline groove axially align and receive a spline therein to axially interlock the two polymer pipes to form a pipe joint assembly.

A piping system including each of a first pipe comprising a bell end and a groove formed in the bell end and a gasket positioned within the groove; a second pipe comprising a spigot end, the spigot end position within the bell end of the first pipe and in contact with the gasket; a bell end reinforcing device positioned external to at least a portion of the bell end of the first pipe, the bell reinforcing device providing structural reinforcement to an exterior surface of the bell end. The piping system may also comprise a pipe stop where the pipe stop mechanically interfaces with the bell reinforcing device to inhibit relative axial movement between the first pipe and second pipe, such as by a dovetail connection.

A pipe connector for connecting at least two pipes, wherein the pipe connector has a first receptacle with a first insertion opening for inserting a pipe and a second receptacle with a second insertion opening for inserting a pipe, wherein the pipe connector has at least one preferably circumferential stop arranged between the first and the second insertion opening on an inner side of the pipe connector, which stop determines a maximum insertion depth of a pipe into the first and/or second receptacle, the pipe connector having at least one, preferably circumferential, sealing lip arranged on the inner side of the pipe connector between the first and/or the second insertion opening and the stop, characterized in that the pipe connector comprises a flexible region of a deformable, compressible or expandable and/or elastic material arranged between the first and the second insertion opening, so that the first receptacle is translationally and/or rotationally displaceable relative to the second receptacle. The invention further relates to corresponding arrangements of a pipe connector having at least two pipes connected thereto.

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.
