ABSTRACT:
A locking means for securing pipe segments in end-to-end relationship wherein at least one pipe segment is slidably disposed within a sleeve member, and having cooperative grooves provided in the pipe segment and the sleeve member to provide an annular chamber when the pipe segments are coupled. A plurality of circular disc members having a diameter substantially equal to the sum of the depth of the grooves are inserted in the annular chamber for locking said coupling in place and providing high load capabilities with ease of coupling and uncoupling.
