    • A pipe joint for joining two pipes (10,11) end to end comprises a hollow cylindrical spigot portion (2) having an annular projection (1) on the outer periphery of a base end thereof, a hollow cylindrical socket portion (4) having an inside diameter approximately equal to the outside diameter of the spigot portion (2) and formed with two opposed apertures (3) in its peripheral wall close to a forward end thereof and with a stepped part (4b) on the inner surface of the peripheral wall for the projection (1) to come into contact with, the stepped part (4b) being closer to a base end of the socket portion (4) than the apertures (3), and a stopper (6) having a pair of circular-arc resilient legs (5) fittable into the respective apertures (3) from outside to project inward and each having a slanting inner surface (5a), the legs (5) being opposed to each other for the inwardly curved surfaces thereof to face each other. The projection (1) is fixedly held between the stepped part (4b) and the legs (5) by inserting the stopper (6) into the apertures (3) with the slanting surfaces (5a) facing toward the insertion side of the spigot portion (2) and inserting the spigot portion (2) into the socket portion (4) until the projection (1) moves past the legs (5). The spigot (2) and socket portions (4) are provided at the joint ends of the two respective pipes (10,11) to be joined.
    • 一种用于首尾相接地连接两根管子(10,11)的管接头包括一个中空圆柱形插口部分(2),该插口部分在其基端的外圆周上具有一个环形突起(1),一个中空圆柱形插座部分(4) 内径近似等于插口部分(2)的外径,并且在靠近其前端的圆周壁上形成有两个相对的孔(3),并且在外围的内表面上具有台阶部分(4b) 所述台阶部(4b)比所述孔(3)更靠近所述插座部(4)的基端,所述突起(1)与所述突起(1)抵接,所述台阶部(4b)具有一对圆形 - 从外侧装入相应的孔(3)并向内突出并且每个都具有倾斜的内表面(5a)的腿部弹性腿(5),腿(5)彼此相对以使其向内弯曲的表面面对每个 其他。 通过将倾斜表面(5a)面向插口部分插入侧的止动器(6)插入孔(3)中,突起(1)固定地保持在台阶部分(4b)和支腿(5) (2)并将插口部分(2)插入插座部分(4)直到突起(1)移动通过腿部(5)。 插头(2)和插座部分(4)设置在待接合的两个相应的管(10,11)的接头端处。
