ABSTRACT:
Mechanical pipe adapters are provided by this invention which include a gland for fitting around the circumference of a first pipe. The gland includes an annular recess located along its inner diameter and an aperture through a side wall of the gland for communicating with the annular recess. The adapter further includes a flexible spline inserted into the annular recess through the side aperture. The flexible spline forms a mechanical lock between the first pipe and the gland. After mounting the gland to a pipe, such as a PVC pipe, the gland can be thereafter mounted to a flanged end of a pipe, e.g., a cast iron fitting.
