Second embodiment of the connector

Referring to fig. 10, the present embodiment is different from the first embodiment of the connector in the structures of the first clip assembly 4 and the second clip assembly, specifically, in the present embodiment:

the first clamp assembly 4 includes a fifth hoop member 41 and a sixth hoop member 42, each of the fifth hoop member 41 and the sixth hoop member 42 resulting in a tubular shape, each of the fifth hoop member 41 and the sixth hoop member 42 being nested on the first flow conduit, with the fifth hoop member 41 being located at the first end of the first telescoping section and the sixth hoop member 42 being located at the second end of the first telescoping section.
