| 摘要 |
A clamp structure which includes a clamping band with open ends adapted to be interconnected and with an ear for tightening the clamping band about an object to be fastened by plastic deformation of the ear; the free ends of the clamping band are provided with arched surface portions, as viewed in transverse cross section, to provide outwardly extending, groove-like reinforcing embossments, and at least one end of the band is of tapered configuration, as viewed in the circumferential direction thereof, with the tapering side surfaces converging toward each other in the direction toward the respective band end so that the arched surface portion of the one band end is able to engage in the overlying arched surface portion near the other band end to assure thereby a continuously smooth, stepless internal configuration of the band during tightening thereof by contraction of the ear as the diametric dimension is reduced. |
