Claims (1)

[Scope of utility model registration request] It consists of a plug 1 that is attached to the terminal end of a fixed pipe such as a gas tank, and a socket 2 that is connected to this plug and to which a flexible pipe is connected on the downstream side. 24 is in a protruding state when plug 1 and socket 2 are connected, and in a non-protruding state, plug 1 and socket 2 are in a disconnected state, and is fixed to the fixed piping terminal part. Cylinder 12
A through hole 13 is formed in the side wall of the fixed cylinder 12, and a locking ball 14 is loosely installed in the through hole 13, and on the outside of the fixed cylinder 12,
A sliding tube 16, which has a raised portion 15 corresponding to the locking ball 14 on its inner surface and slides by a certain stroke, is fitted onto the outside, and the sliding tube 16 is lightly biased in the projecting direction by a first spring 17. On the other hand, a plug 1, which is lightly biased in the protruding direction by a second spring 11, is slidably inserted into the fixed cylinder 12, and the outer periphery of the plug 1 corresponds to the locking ball 14. A flexible tube connection in which a recessed groove 18 is provided so that the locking ball 14 and the corresponding raised portion 15 and recessed groove 18 are aligned with each other when the socket 2 is in an unconnected state.
