1. An enteral adapter assembly comprising:
an enteral fluid source having a fluid outlet provided with a screw thread;
an adapter including a proximal end comprising a first connection portion for attaching to the fluid outlet, a distal end comprising a first threaded connection portion for screwing to an end of an enteral feed tube, and a fluid conduit extending between the proximal end of the adapter and the distal end of the adapter, and
a removable cap having a second threaded connection portion configured for screwing the cap onto the first threaded connection portion,
wherein the first connection portion of the proximal end of the adapter includes a third threaded connection portion configured for forming a screw connection with the screw thread of the fluid outlet to form a fluid-tight connection between the fluid outlet and the fluid conduit,
wherein the proximal end of the adapter further comprises a locking member configured to irreversibly mate with a corresponding feature provided on the fluid outlet as the adapter is screwed on to the fluid outlet to prevent removal of the adapter from the fluid outlet and consequent failure of the fluid-tight connection when the cap is unscrewed from the distal end of the adapter,
wherein the locking member comprises at least one deflectable element that is configured to deflect in a longitudinal direction towards the distal end of the adapter as the adapter is screwed on to the fluid outlet and thereby irreversibly mate with the corresponding feature provided on the fluid outlet.
