Abstract
A spline for joining irrigation tubing includes an elongated body portion. The body is configured to be inserted into and substantially fill a channel formed by aligning an interior channel in a female tubing end and a corresponding exterior channel in a male end. One or more serrations or slots in the body facilitate bending the body into annular channels. The end of the body is tapered to facilitate its insertion, including a taper along its length (such as on the side opposite the serrations), and a gripping portion on the spline further facilitates insertion and removal. Related methods are disclosed.
