Separation-preventive type pipe joint

摘要

A slip-on type pipe joint wherein a ringlike seal packing is mounted in an annular recess formed in the inner peripheral surface of the socket end of one pipe and the spigot of another pipe is inserted, whereby the pipes are connected together. The pipe joint is characterized in that the inner peripheral surface of the socket is formed with an engagement projection projecting toward the axis of the pipe and disposed adjacent the inner side of the packing, a split lock ring axially engageable with the engagement projection is fitted in an annular groove formed in the outer peripheral surface of the spigot, and the opposed free ends of the split lock ring are joined together by a coupling piece placed on the lateral surface of the split lock ring disposed adjacent the front end side of the spigot to prevent the split lock ring from slipping off the annular groove.
