ABSTRACT:
A joint which is made up of exhaust pipes formed with beaded ends or with a beaded end on one pipe and a flared end on the other pipe, in any case either with or without suitable gasket means. A clamp having a concave groove engages the protrusions on the ends of the pipes of the joint and wedgingly forces them together as the clamp is constricted.
The clamp is made out of two halves which are hingedly connected at the first end of each and which are adapted to be secured by a bolt at the second end of each, there preferably being a nut permanently welded to one of the second ends coaxial with a first perforation in that end and a second perforation in the other of the second ends to pass the bolt to the nut. The hinged connection is preferably non-separable.
