管连接单元和制造该管连接单元的方法
摘要：
一种管连接单元，包括：具有阳连接件的第一管构件、具有阴连接件的第二管构件、和连接第一管构件和第二管构件的管连接构件。阳连接件容纳在阴连接件中，从而使得阳连接件的外周表面与阴连接件的内周表面相对。管连接构件包括在径向方向上弹性地可移动的接合部件，并且管连接构件与第一和第二管构件接合。阳连接件和阴连接件分别包括位于外周表面和内周表面上的旋转限制部件，用于限制第一和第二管构件的相对旋转。
摘要（英）：

A pipe joint unit includes a first pipe member with a male joint, a second pipe member with a female joint, and a pipe joint member coupling the first pipe member and the second pipe member. The malejoint is received in the female joint such that an outer peripheral surface of the male joint is opposed to an inner peripheral surface of the female joint. The pipe joint member includes an engagement part that is elastically displaceable in the radial direction, and engages with the first and second pipe members. The male joint and the female joint have rotation restricting parts on the outer peripheral surface and the inner peripheral surface, respectively, for restricting relative rotation of the first and second pipe members.
