Title:
FASTENING DEVICE FOR FLUID PIPE
Document Type and Number:
Japanese Patent JP3904697
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To facilitate handling and mounting work by connecting end parts of each fastening piece opposed to a circumferential direction to each other by a connecting means freely to detach them and freely to elastically deform them in the radial direction so as to enlarge, in a ring shape, an inner diameter having a diameter larger than an external shape of a fluid pipe.
SOLUTION: Flexible pieces 11b having a thin wall are continuously arranged in parallel with each other on vertical both end parts of a base part freely to elastically deform, a size between the flexible pieces 11b is formed in the same or somewhat smaller size as the groove width of a connecting groove 2, and a lock piece 11c is continuously arranged at a tip end of the flexible piece 11b freely to engage with the stage enlarging part 12a of the connecting groove 12. Respective fastening pieces 10 are connected to each other in a ring shape by inserting a connector 11 into each connecting groove 12 formed on the end surface of the fastening piece 10 from a side direction. In this time, the inner diameter of the fastening device is elastically push-opened in a diameter enlarging direction so as to form the inner diameter some larger than the external shape of a water pipe. It is thus possible to improve handling and mounting workability, and it is also possible to prevent a damage from generating on a part other than an assigned position.
