2. Description of the Related Art A clamp band made of stainless steel or other metal band material cut to a certain length is wound into a circular ring shape partially overlapping one end side and the other end side to form a three-dimensional shape. In addition, as a clamp member of a pull-drawing operation type in which the diameter of the clamp band is artificially forcibly deformed and contracted by a pulling operation such as a pliers or a nipper, JP-A-4-210188, JP-B-5-63641, Patent No. 2758968, No. 2
No. 758969 has been proposed, and each of them has a form in which there is no protruding ear portion which is crushed by a special caulking tool, so that the weight distribution in the circumferential direction is largely non-uniform and does not interfere with surrounding members in use. In all respects, they are all in common.

[0003] Among them, in the case of Japanese Patent Application Laid-Open No. Hei 4-210188, in particular, the vicinity of the first end (13) in the outer overlapping portion (22) of the band body (11) and the intermediate portion (23) of the band body (11). ), The first and second tool hooking portions (40) and (45) are both formed to protrude outward, and furthermore, the temporary fixing projections (55) which protrude outward from the inner overlapping portion (21). ) And a receiving portion (58) of a projection receiving hole (57) that opens to the outer overlapping portion (22). The temporary fixing means (59) is provided on the band body (11). It is considered to be a known invention that most closely resembles the invention.

[0004]

However, according to the structure of the known invention, the provisional fixing projection (55) is also engaged in the provisional engagement with the receiving portion (58) of the projection receiving hole (57). The locking projections (35) and (35) separate from the first and second locking holes (30a) and (30b) enter and lock.

[0005] Therefore, the drawing operation is performed by drawing from the temporary fixing state shown in FIGS. 1 to 3 to a so-called final tightening state shown in FIGS. To the stop hole (30a), the locking projection (35) separate therefrom
In the transition process in which (35) enters the second and third locking holes (30b) (30c), these inner overlapping portions (2
Projection group (35) (35) projecting outward from 1)
(55) is strongly pushed inward by the outer overlapping portion (22), and the temporary fixing projection (5)
5) The back (55b) forms a smooth inclined surface,
The bulging portions (37) (3) of the locking projections (35) (35)
7), the projections (35), (35), and (55) may buckle improperly in combination with the smooth arch shape.

As shown in FIG. 10, the front walls (36) and (36) of the locking projections (35) and (35) have a protruding height greater than the plate thickness of the band body (11) and have an outer overlapping portion. It rises in a substantially vertical direction from the surface of (22), and in the final tightening state, it is overlapped with the front edges (31) and (31) of the second and third locking holes (30b) and (30c). In addition to the terminal overlapping portion (22), the first end (13) of the outer overlapping portion (22) does not rise, so that the terminal holding portion (50) projects outward from the inner overlapping portion (21) in the tunnel. It is also to be inserted into.

For this reason, it is impossible to manually release the final tightened state shown in FIGS. 6 to 10 and to use the clamp again, which limits its use. In other words, in the above-mentioned known invention, in the maintenance / inspection work of the equipment, if the hose or the boot needs to be replaced, the fastening state of the clamp is released and reuse is not considered at all.
