ていた。 In this type of device, a clamping fitting having a contact tube fitting hole is provided with a longitudinal slit extending to one side of the fitting hole, and the separation piece separated through the slit is inserted into the slit. Generally, the bolt is tightened using a tightening bolt extending transversely to the bolt, but when doing so, there are disadvantages such as the machining of the fastening fitting is labor-intensive and the tightening fitting becomes large.

る。 The purpose of the present invention is to improve such inconveniences, and a through hole 4 is provided in the fastening fitting 3 having the fitting hole 2 of the contact tube 1, which intersects the fitting hole 2 at right angles. A contact tube 1 is inserted into the through hole 4.
It is characterized in that a lock pin 6 having an arcuate groove 5 in contact with the outer periphery of the lock pin 6 is mounted so as to be freely tightenable in the axial direction.

果を有する。 In this way, according to the present invention, the fastening fitting 3 having the fitting hole 2 of the contact tube 1 is provided with a through hole 4 that intersects orthogonally with the fitting hole 2, and the contact is inserted into the through hole 4. Since a lock pin 6 having an arcuate groove 5 in contact with the outer periphery of the tube 1 is attached so as to be able to be tightened in the axial direction, the contact tube 1 inserted into the insertion hole 2 can be tightened in the axial direction by the lock pin 6. Since it is fastened, it is easy to tighten, and since it is sufficient to provide the through hole 4 perpendicularly to the insertion hole 2 in the fastening metal fitting 3, the processing is easy and the size is reduced. It has the effect of being able to.
