A pipe coupling is provided to obtain long life span of the pipe coupling without sensitivity to dynamic load by installing clamping members on a molding shell and covering a sleeve with clamping straps directly. A pipe coupling(25) comprises a clamping device having a ring shaped sleeve(11) made of an elastic material, more than two clamping straps(12,13) and more than two clamping screws(14), and clamping the sleeve. The clamping straps have ends(15) forming roofs. The ends of the roofs include a part covering clamping bolts(18), and a part(17) combining the ends with an outer surface(19) of the clamping strap. The ends are guided to the outer surface of the clamping strap so that a part(20) between the two parts is extended to the outer surface of the clamping strap. A sleeve is partially covered with a molding shell on which more than two tightening members are installed to tighten the sleeve.
