Abstract
Provided is a hose connector that is protected from inadvertent disconnection, and permits any problem with the hose connection to be readily detected. The hose connector () includes a connector main body (), and a lock member () fitted on the connector main body. When the lock member () is displaced to a locked position, an annular reduced diameter portion () of the lock member () approaches an annular enlarged diameter portion () of the connector main body () so that these two portions clamp the wall of the hose. The lock member () is held in the locked position by a second engagement portion () formed in the inner circumferential surface of the lock member () engaging the connector main body (). When the lock member () placed in the locked position is subjected to a twisting force exceeding a prescribed value, a frangible part () provided between the second engagement portion () and the annular reduced diameter portion () fractures, but the connection of the hose is maintained because the second engagement portion supports the annular reduced diameter portion from the rear via the frangible part ().
