1. A fluid connection assembly, comprising:
a fluid connection adapter having first and second adapter ends, the fluid connection adapter providing a raised lock engagement surface and an adapter release collar on an external surface of the fluid connection adapter, the fluid connection adapter further providing at least a first seal section;
a fluid connection housing assembly having first and second housing ends, the fluid connection housing assembly providing a displaceable locking ring, a plurality of locking elements, and at least a first seal bore;
wherein each locking element is disposed to constrict radially;
wherein each locking element has a locking element outer surface and a locking element inner surface;
wherein, during entry of the second adapter end into the first housing end, the first seal section sealingly contacts the first seal bore, wherein the first seal section is disposed to expand radially such that when the first seal section expands radially, the first seal section further tightens sealing contact against the first seal bore;
wherein engagement of the locking ring on the locking element outer surfaces causes the locking element inner surfaces to retain the fluid connection adapter via the lock engagement surface; and
wherein engagement of the locking ring on the adapter release collar causes the first seal section to release sealing contact with the first seal bore.
