ABSTRACT:
A pipe connection, particularly useful for a motor vehicle exhaust line, is provided with a spherical sealing surface on one pipe which projects into an axial accommodating space on a mating pipe. The pipes are held together by spring clamps which have opposite ends facing each other for engaging oppositely facing recesses on clamping structures (e.g., flanges) associated with each pipe. The spring clamps are constructed as C-shaped leaf springs having rounded ends.
