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. In the exemplary embodiment of the invention, the notch is machined part-way into the second one of the walls. The detent may be a dent punched into the first one of the walls. The notch may be cylindrical in shape. In the exemplary embodiment of the invention, the notch is formed in the male wall and the detent is formed in the female wall. One embodiment of the invention includes a clamp having retaining members with grooves circumscribing at least part of the flanges with the male wall received within the female wall. The grooves and the flanges are tapered.
