<P>PROBLEM TO BE SOLVED: To provide a clamp device 1 for connection which allows a tightening force to a hose 2 to be visually checked to facilitate external determination whether the tightening force is proper or not during inspection, and allows easy management of the tightening force, thereby enabling proper quality control. <P>SOLUTION: In rotating a screw 8, a tensile force F in a circumferential direction W2 is applied directly to a strap band 3, so that the tensile force F serves as a highly reliable index of the tightening force. A test table showing a relation between displacement Δ1, Δ2 of a displaceable part 13 and a tensile force F or a tightening force is prepared. The displacements Δ1, Δ2 visually indicate the actual tightening force to facilitate determination with a simple means whether the hose 2 is tightened with a proper tightening force or not, thereby facilitating management. <P>COPYRIGHT: (C)2012,JPO&INPIT |
