Abstract
Tubular telescoping members have interrupted circumferential lugs which engage through relative axial movement followed by relative turning movement of the members. A releasable locking device prevents reverse relative turning movement of the members and comprises a plurality of threaded lock elements engaging internally threaded openings in an outer tubular member near its terminal shoulder. Each lock element is installed from the inside of the outer member, and has a portion accessible exteriorly of the outer member. Each lock element has a circular flange which projects beyond the terminal shoulder and into a detent provided on an external annular shoulder on the inner member. The circular flange is interrupted at one location by a flat face which is flush with the terminal shoulder when the lock element is turned one-half revolution.
