Abstract
A connector assembly for establishing a fluid type connection with a pipe or tube having a body member with a bore for receiving the tube, a nut which is in threaded engagement on the body member and an intermediate ring compressed between the nut and the body member and having inwardly extending edge formations which cut into the tube in order to retain it within the connector, the intermediate ring being provided with radially outwardly extending axial ribs which cooperate with the body member and the nut to prevent unintentional overtightening of the nut. The ribs may have tapered stop faces which engage a tapered bore portion in the nut and a radial or tapered surface adapted to engage with the body member of the connector assembly.
