<P>PROBLEM TO BE SOLVED: To provide a connection device for piping by which connection between pipes or between a pipe and a piping appliance, and separation thereof can be simply and promptly carried out without using screws, and rotation in the state of connection is possible to responde to versatile conditions. <P>SOLUTION: The connection device for piping comprises a 1st pipe body 2A, a 2nd pipe body 3A, and a C-type elastic member 4A. The 1st pipe body 2A has a receiving tube 22 at one end, and a connection tube 21 at the other end as a connection means to a pipe or piping appliances. The 2nd pipe body 3A has an insertion tube 31 at one end, and a connection tube 32 at the other end as a connection mens to a pipe or piping appliances. The C-type elastic member 4A is wound around the insertion tube 31. The C-type elastic member 4A is radially reduced so as to insert the insertion tube 32 to the depth of specified length of the receiving tube 22, then the C-type elastic member 4A is radially expanded. As a result the receiving tube 22 and the insertion tube 31 are locked so that the 1st pipe body 2A and the 2nd pipe body 3A are mutually rotatably connected. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
