Abstract: A pipe connection includes a longitudinally extending first pipe portion having an annular first flange at a first distal end of the first pipe and a longitudinally extending second pipe portion having an annular second flange at a second distal end of the second pipe. One of the flanges is a male flange and the other of the flanges is a female flange. The male flange has a ring shaped male wall longitudinally extending from a longitudinally facing flat surface of the male flange. The female flange has a ring shaped female wall longitudinally extending from a longitudinally facing first flat surface of the female flange. The male and female walls are shaped and sized such that the male wall is received within the female wall. A detent is formed from, in, and extending radially away from a first one of the walls toward a second one of the walls. A notch extends radially into the second one of the walls and is sized and shaped to receive the detent therein.
