Abstract
A collet-type pipe coupling of simplified construction includes three main flange parts and a grip structure. The main flange parts are machined or otherwise formed with plain shapes. One flange is welded to an associated length of pipe or other body and all of the flanges are assembled over a separate length of pipe. A first set of bolts is tightened to compress a packing carried in the welded flange with an intermediate flange. A second set of bolts draws a flange collar towards the intermediate flange to constrict the grip structure radially into locking engagement with the separate length of pipe to complete a coupling installation.
