ABSTRACT:
The present invention provides a two-loop coiled type clamping device for semipermanently fixing a fluid conveying hose, dustproof bellows, axial boot or other article to be fixed 10 to the circumferential connecting surface 32 of a mating device 31, characterized in that in order to elastically accommodate changes in the hardness or thickness of the article 10, it is arranged that in a region where the inner and outer overlap portions 11a and 11b of a clamp band 11 overlap each other through the intermediate overlap portion 11c in three layers by a fixed amount X, a first fixing tooth 18 directed inwardly of the outer overlap portion 11b and a second fixing tooth 22 directed outwardly of the intermediate overlap portion 11c come in seizure engagement with each other and in a region where two-layer overlapping takes place excluding said fixed mount X, a plurality of float leg pieces 23 interposed between the external and internal contact regions X1 and X2 enables the clamp band 11 to store diametrically directed spring force.
