An adaptor (45) for converting to a push-to-connect tube fitting/port a standard tube fitting/port body (10) having a threaded portion (11) for threaded attachment of a nut/plug (12) , comprises a coupling nut/plug (12) having an axially inner threaded end portion for threaded attachment to the threaded portion (11) of the fitting/port body (10) ; a tube sealing member (15) contained within the nut/plug (12) for sealing to a tube (19) having a locking surface (22) spaced from the end of the tube (19) ; and a retention device (23) retained in the nut/plug (12) , which nut/plug (12) has at an axially outer end thereof a central opening through which the tube (19) can be inserted into the coupling nut/plug (12) , whereby the locking surface (22) can be engaged by the retention device (23) to prevent axial withdrawal of the tube (19) from the coupling nut/plug (12) once inserted; wherein sealing and retention of the tube (19) is effected within the confines of the coupling nut/plug (12) and separate from and without requiring modification of the standard tube fitting/port body (10) . |
