This makes it possible to change the state in which the cover body covers the fastening and holding mechanism and the state in which it is not covered.

  Preferred embodiments of the present invention (how best to carry out the invention) will be briefly described with reference to the drawings and the effects thereof.

  For example, when the cover body 8 is rotated with respect to the clamp b so as to cover the clamping and holding mechanism 5 of the clamp b that clamps and holds the pipe a, the cover body 8 becomes a projecting portion of the clamp b. The clamping and holding mechanism 5 is in a state of being covered from the outside, so that an object is hardly caught on the outer surface of the clamp b.

  In addition, for example, the clamp b that clamps and holds the pipe a so as not to cover the clamping and holding mechanism 5, that is, the clamp b so that the clamping and holding mechanism 5 is exposed. On the other hand, when the cover body 8 is rotated, the cover body 8 separates from the tightening and holding mechanism 5 and the tightening and holding mechanism 5 is exposed, whereby the tightening and holding mechanism 5 is tightened. It will be in a state in which hugging operation can be performed.

  Therefore, by simply rotating the cover body 8 with respect to the clamp b, the tightening and holding mechanism 5 which becomes the projecting portion of the clamp b which tightens and holds the pipe a is covered with the cover body 8 so that the object is hardly caught. In addition, it is possible to easily change the state in which the tightening / holding mechanism 5 is operable by setting the cover body 8 to an exposed state without covering the tightening / holding mechanism 5 with the cover body 8.

  Further, for example, the cover body 8 is made of resin, and the cover body 8 is formed on the outer surfaces of the holding body 1A and the fastening holding body 1B and the fastening and holding mechanism 5 or the holding body 1A. Alternatively, if the clamp holder 1B is formed to have a shape capable of covering the outer surface of the clamp holder 1B and the clamp holder 5, the clamp b as well as the clamp holder 5 which becomes the projecting portion of the clamp b can be used. Since the outer surface, that is, the outer surface of the holding body 1A and the tightening holding body 1B or the outer surface of the holding body 1A or the tightening holding body 1B can be covered with the cover body 8, the clamp is further improved. An object can be hardly caught on the outer surface of b.

  In addition, by making the cover body 8 made of resin, cushioning (elasticity) can be imparted, and thereby, even if an operator comes into contact with the outer surface of the clamp b, for example, the impact at the time of contact can be reduced. Therefore, it can be made more secure.

  In addition, since the cover body 8 is made of resin, for example, it can be manufactured by integral molding, it can be easily manufactured, and excellent mass productivity can be exhibited.

  Also, for example, the fastening and holding mechanism 5 is provided on the fastening bolt 2 provided on the holding body 1A or the holding body 1B and on the fastening and holding body 1B or 1A. And a nut 4 screwed onto the tightening bolt 2 engaged with the engaging locking portion 3 or an engaging portion provided at an end of the holding body and an end of the tightening holding body. A wedge body which fits into an engagement portion provided at an end of the holding body 1A and an end of the fastening holding body 1B to tighten and connect the holding body 1A and the fastening holding body 1B; , And the nut 4 screwed to the tightening bolt 2 of the tightening and holding mechanism 5 on the cover body 8, or the end of the holding body and the tightening and holding body And an accommodating portion 13 which is capable of accommodating a wedge body which is fitted into the end portion and which tightens and connects the holding body 1A and the fastening holding body 1B by fitting into the engaging portion. By rotating the cover body 8 with respect to the clamp b and storing the tightening and holding mechanism 5 in the storage portion 13, the tightening and holding mechanism 5 is covered with the cover body 8. With this configuration, even if the tightening and holding mechanism 5 of the clamp b is composed of the tightening bolt 2 and the nut 4 screwed to the tightening bolt 2, the end of the holding body 1A and the tightening Even when the holding body 1B includes an engaging portion provided at an end portion of the holding member 1B and a wedge body that fits into the engaging portion, the fastening body 5 serving as a projecting portion of the clamp b is fixed to the cover body 8 by the cover body 8. This is more practical, for example, because it is possible to securely cover and prevent an object from being caught on the outer surface of the clamp b.

  Further, for example, when the cover body 8 covers the clamping and holding mechanism 5 which is a projecting portion of the clamp b which clamps and clamps the pipe a, the cover body 8 is pressed into the clamping and holding mechanism 5 and the cover body 8 is pressed. If the press-fitting portion 16 for holding the state of covering the clamping and holding mechanism 5 is integrally formed inside the cover body 8, the cover body 8 is rotated with respect to the clamp b which clamps and holds the pipe a. By press-fitting the press-fitting portion 16 of the cover body 8 into the tightening and holding mechanism 5, the state in which the tightening and holding mechanism 5 of the clamp b is covered with the cover body 8 can be favorably held. Even if a force is applied from the outside that causes the cover 8 to rotate in a direction that does not cover the fastening and holding mechanism 5, the rotation of the cover body 8 can be suppressed, and the press-fitting portion 16 can be easily formed. It becomes more practical, for example, because it can be formed in any form.

  Further, for example, at one end of the cover body 8, an engaging portion 6 for engaging the cover body 8 with the clamp b is provided, and at the other end, a storage portion 13 capable of housing the fastening and holding mechanism 5 is provided. When the cover body 8 is rotatably disposed with respect to the clamp b by engaging the engaging portion 6 with the clamp b, only the engaging portion 6 is engaged with the clamp b. The cover body 8 can be disposed rotatably with respect to the clamp b, whereby the cover body 8 can be easily disposed on the clamp b, and the cover body 8 covers the clamping and holding mechanism 5 and does not cover it. It becomes more practical, for example, the state can be changed.
