The present invention provides a joint cover capable of improving working efficiency in mounting a joint cover on a joint. A joint cover provided on the outside of a joint includes a first cover body provided with an opening and adapted to house one side of the joint; and a second cover body detachably attachable to the first cover body, wherein a dividing position formed when the first cover body and the second cover body are in contact with each other is offset toward the second cover body.

Joint cover

A connection-structure of a flexible tube, in which the flexible tube is fitted to an end portion of a metal pipe, comprises an annular projection, a first radially enlarged portion, a seal ring and a second radially enlarged portion. The annular projection is formed on an outer surface of the end portion of the metal pipe. The first radially enlarged portion is formed on the tip side of the metal pipe relative to the projection, defining a first annular groove with the projection. The seal ring is fitted into the annular groove. The second enlarged portion is formed on the base side of the metal pipe relative to the projection, defining a second annular groove with the projection. The tip portion of the flexible tube is positioned close to the maximum diameter portion of the second enlarged portion.

Connection-structure of a flexible tube

A device having a tube for heating or heat retaining of fluid includes a first path in which a connection section of a cord heater led out of the tube and a lead wire connected to a power supply is provided, a second path provided between the tube and the first path, and a drainage path for removing leaked fluid of the second path. In this device, the connection section is sandwiched by a pair of first sealing members to retain a sealed state and the cord heater passes through the second path in a sealed state by a second sealing member. This device can effectively prevent gas or liquid from leaking into the space where the connection section of a lead wire and a cord heater is provided.
