| 摘要 |
The invention relates to an open-type hose clamp. The invention provides a clamp, comprising clamping band means (111) having clamping band end portions intended to form overlapping inner and outer band portions (111b and 111a) in the installed condition, a connection operable to connect overlapping band portions, a plastically deformable tightening device (13, 113) for tightening the clamping band means about an object to be fastened thereby, said tightening device requiring an initial plastic deformation for proper functioning, characterized in that said connection includes a lost-motion means (131, 170; 231, 331; 431) enabling partial contraction of the tightening device (13, 113) during at least a part of the initial plastic deformation substantially without change in the diametric dimension of the clamp. |
