Abstract

An insertable type safety coupling for pressure pipes has a coupling socket inside which is swivellingly mounted a locking member and into which a nipple may be inserted for coupling and uncoupling without pressure. The locking member may be secured against swivelling at least in its through-position in the pipe by means of at least one bolt or cam.
The bolt or cam is slidingly guided on the coupling socket and in its blocked position it engages a bore or recess in the locking member. The locking member has a recess that extends around its throughbore in a perpendicular direction to its pivoting axis. An adapter with a through bore is form-fittingly and sealingly set into the recess of the locking member. The inside of the adapter is designed as a socket for the nipple.
