    • The present invention provides a pipe coupling socket having a main body containing a plurality of lock balls for locking a plug accepted in the main body. The main body has a projecting lock portion which projects from the outer circumferential surface and has a top surface in which a groove is formed. The operation sleeve has a stepped portion formed in the circumferential direction on the inner surface thereof, such as to engage with an axial end of the projecting lock portion, thus inhibiting the operation sleeve from transferring to the rear end portion side, a lock releasing recess recessed in the stepped portion such as to house an axial end of the projecting lock portion, thus allowing the operation sleeve to transfer to the rear end portion side, and protruding portions which can be fitted to the groove when the projecting lock portions are placed at a position which matches the lock releasing recess in the axial direction, and at a position which is offset from the lock releasing recess in the circumferential direction. The projecting lock portion can go over the protruding portions when the user moves the operation sleeve in the circumferential direction.
    • 本发明提供了一种管接头插座,其具有主体,该主体包含用于锁定接纳在主体中的插头的多个锁定球。 主体具有从外周面突出并具有形成有凹槽的顶面的突出锁定部。 操作套筒具有在其内表面上沿圆周方向形成的阶梯部分,以便与突出的锁定部分的轴向端部接合,从而阻止操作套筒转移到后端部侧,锁定释放凹部 凹陷在阶梯部分中,以容纳突出的锁定部分的轴向端部,从而允许操作套筒转移到后端部侧,以及当突出的锁定部分被放置在其中时可以装配到凹槽的突出部分 与锁定解除凹部沿轴向匹配的位置,以及在周向上与锁定释放凹部偏移的位置。 当用户沿圆周方向移动操作套筒时,突出的锁定部分可以越过突出部分。
