Claim 0:
1. A pressurizable assembly for facilitating the flow of a fluid from a wellhead to pressurized equipment and vice versa, the pressurizable assembly comprising:
a first assembly having a wellhead connection member which facilitates a releaseable connection with the wellhead, and the first assembly defining a first assembly fluid passageway axially through the first assembly;
a second assembly having an equipment connection member which facilitates a releaseable connection with the pressurized equipment, and the second assembly defining a second assembly fluid passageway axially through the second assembly;
the first assembly carrying one of:
1) at least one spring loaded locking pin, or
2) at least one cam groove defining a one way passageway for the locking pin through the cam groove,

while the second assembly carrying the other of:
1) the at least one spring loaded locking pin and
2) at least one the cam groove defining a one way passageway for the locking pin though the cam groove;
when the first assembly engages with the second assembly, by a relative downward movement of the second assembly relative to the first assembly to a lower most position then followed by a relative upward movement, the at least one locking pin follows the at least one cam groove in a first direction and the first and the second assemblies become locked to one another and the first assembly fluid passageway and the second assembly fluid passageway form a fluid-tight seal therebetween which permits the flow of the fluid between the wellhead and the pressurized equipment; and
when the second assembly is subsequently moved, downward and then upward, relative to the first assembly, the at least one locking pin continues following the at least one cam groove in the first direction and the first and the second assemblies become disengaged and separated from one another.
