Medical connector

A luer connector comprising:

• a first housing member comprising a first end, a second end, and a first connector engagement portion configured to engage a first connector and positioned at the first end;
• and
• a second housing member comprising:
• a first component defining a first cylindrical surface including at least one engaging surface, the first component being coupled to the first housing member so as to be inhibited from rotating relative to the first housing member,
• a second component defining a second cylindrical surface including at least one engaging surface, the second cylindrical surface being generally co-axially aligned with and adjacent to the first cylindrical surface, the second component being supported by the first component and comprising a second connector engagement portion configured to engage a second connector,
• a first arrangement in which the at least one engaging surface of the second component is configured to interact with the at least one engaging surface of the first component to inhibit the second component from rotating in either a first direction or a second direction relative to the first housing member, and
• a second arrangement in which either the at least one engaging surface of the second component or the at least one engaging surface of the first component is configured to permit the second component to substantially freely rotate in either the first direction or the second direction relative to the first housing member after a predetermined amount of manual torque is applied to the second component relative to the first housing member,
• wherein the first direction is defined as a direction that permits the second connector to threadably engage the second component and the second direction is defined as a direction that permits the second connector to threadably disengage the second component, and
• wherein the second housing member is configured to change from the first arrangement to the second arrangement when the second connector is further rotated in the first direction beyond a point at which the second connector is substantially fully engaged with the second housing member.
