(First clamp 100)
A first clamp 100 shown in FIG. 1 holds a saddle joint 11 arranged on the first outer peripheral surface 20 a of the main pipe 20 . As shown in FIG. 1, the first clamp 100 comprises a first member 110 and a second member 120. As shown in FIG. In this embodiment, the first member 110 and the second member 120 are made of resin. As for the molding method, for example, integral molding by injection molding or shaving by cutting is preferably used.
The first member 110 includes a first placement portion 111 , a first engaging portion 112 , a first belt-like member 113 (connecting belt), a first reinforcing member 114 and a handle 115 .

The first arrangement portion 111 is arranged on the first saddle collar 14 of the saddle joint 11 . The first arrangement portion 111 is a rod-shaped member whose longitudinal direction is provided in the axial direction. One end of the first belt-shaped member 113 is connected to both ends of the first arrangement portion 111 in the longitudinal direction. Therefore, the length of the first placement portion 111 is formed to be at least longer than the axial length of the first saddle brim 14 so that the first saddle brim 14 and the first belt-shaped member 113 do not interfere with each other.

The first engaging portion 112 engages with a second engaging portion 122 provided on the second member 120 . The first engaging portion 112 is formed at the other end of the first belt-shaped member 113 . The first engaging portion 112 has a male saw blade shape. As shown in FIG. 3, the male saw blade has an inclined surface 112a inclined with respect to the traveling direction D and an orthogonal surface 112b perpendicular to the traveling direction D, which are continuously provided. It is uneven. The advancing direction D is the direction in which the first engaging portion 112 advances relative to the second engaging portion 122 when the first engaging portion 112 engages with the second engaging portion 122 .

The second projection 113b is a projection provided along the direction orthogonal to the first projection 113a, that is, along the axial direction of the main pipe 20. As shown in FIG. By providing the projections in this way, when the first belt-shaped member 113 is arranged along the circumferential direction of the main pipe 20 , only the first projections 113 a and the second projections 113 b are in contact with the main pipe 20 . By thus reducing the contact area, the tightening force of the first strip member 113 on the main pipe 20 may be improved.

As shown in FIG. 4, the first reinforcing member 114 axially connects the pair of first strip members 113 . This makes it difficult for the pair of first belt-shaped members 113 to be misaligned. The part to be connected is preferably an intermediate point in the circumferential direction of the first belt-shaped member 113 . Alternatively, it may be changed as appropriate according to each design condition. For example, the first reinforcing member 114 may be provided at a position closer to one end side or the other end side in the circumferential direction of the first belt-shaped member 113 . The first reinforcing member 114 may be provided not only at one place but also at a plurality of places in the circumferential direction.

As shown in FIG. 4, for example, the handles 115 are provided at four locations in total, one at each end in the circumferential direction of the pair of first belt-shaped members 113 . Alternatively, the mounting locations and number may be arbitrarily determined as required. Also, in the present embodiment, the handle 115 has a rod shape extending in the axial direction, but it is not limited to this. For example, it may have a ring shape so that it is easy to put a finger on it when engaged.

As shown in FIGS. 6 and 7, the second member 120 is a plate-like member. The second member 120 includes a second placement portion 121 and a second engaging portion 122 . The second member 120 secures the fixation of the saddle joint 11 and the main pipe 20 by engaging with the first member 110 . Specifically, the first engaging portion 112 of the first member 110 and the second engaging portion 122 of the second member 120 are engaged.

The second placement portion 121 is placed on the second saddle collar 15 of the saddle joint 11 . The second placement portion 121 is a plate-like member, and includes a second engaging portion 122 inside the plate-like portion. The axial length of the second placement portion 121 is equal to the interval between the pair of first belt-shaped members 113 .

The second engaging portion 122 engages with the first engaging portion 112 . As shown in FIG. 3 , the second engaging portion 122 is positioned inside the second placement portion 121 . The second engaging portion 122 has a female saw blade shape corresponding to the male saw blade shape of the first engaging portion 112 . That is, as shown in FIG. 6, the first engaging portion 112 has an inclined surface 122a that is inclined with respect to the advancing direction D, and an orthogonal surface 122b that is orthogonal to the advancing direction D. and are provided continuously. In the second engagement portion 122 of the first clamp 100, the female sawtooth shape is provided on both the first side and the second side.

In addition, a plurality of second engaging portions 122 are provided in the direction from the first side to the second side (hereinafter also referred to as the first direction). By appropriately selecting one of the plurality of second engaging portions 122 to engage with the first engaging portion 112, the interference of the main pipe 20 by the first belt-shaped member 113 is adjusted.
As shown in FIG. 7 , the second engaging portion 122 is provided over the entire second placement portion 121 in the longitudinal direction. Alternatively, as shown in FIG. 8, the second engaging portions 122 may be provided only at both ends of the second arrangement portion 121 in the longitudinal direction.

Fixing of the main pipe 20 and the saddle joint 11 by the first clamp 100 having the above configuration is performed as follows. That is, first, the first arrangement portion 111 of the first member 110 is arranged so that its longitudinal direction is along the longitudinal direction of the first saddle collar 14 . As a result, one ends of the pair of first belt-shaped members 113 are arranged at both ends of the first saddle flange 14 in the axial direction.
Next, the second member 120 is arranged so that its longitudinal direction is along the longitudinal direction of the second saddle collar 15 . At this time, the second engaging portion 122 is arranged to face the first saddle flange 14 so that the second engaging portion 122 can engage with the first engaging portion 112 .

In the above-described state, the first engaging portion 112 is engaged with the second engaging portion 122 so as to be pushed. That is, the first engaging portion 112 is advanced in the advancing direction D with respect to the second engaging portion 122 to engage the first engaging portion 112 and the second engaging portion 122 . The traveling direction D is also a direction perpendicular to both the axis of the main pipe 20 and the first direction. At this time, the handle 115 may be held so as to facilitate application of the pushing force. When the first engaging portion 112 is pushed toward the second engaging portion 122, the inclined surfaces 112a and 122a contact each other. As a result, the pushing force acts to spread the second engaging portion 122 . Therefore, the first engaging portion 112 can enter the second engaging portion 122 . When the first engaging portion 112 pushed into the second engaging portion 122 is pulled out, the orthogonal surfaces 112b and 122b contact each other. At this time, the pull-out force does not act in the direction of expanding the second engaging portion 122 . This prevents the first engaging portion 112 from slipping out of the second engaging portion 122 .

By engaging the first engaging portion 112 and the second engaging portion 122 in this manner, the first member 110 and the second member 120 are assembled. That is, the first arrangement portion 111 and the second arrangement portion 121 are connected via the first belt-shaped member 113 . As a result, the main pipe 20 is tightened by the first clamp 100 to fix the saddle joint 11 and the main pipe 20 together. At this time, the first belt-shaped member 113 functions as a connecting belt that connects the first placement portion 111 and the second placement portion 121 .
