Fluid line connectors

A male fluid line connector configured to engage a female fluid line connector, the male fluid line connector comprising:

• a body including
• a first end configured to be connected to a fluid line,
• a tapered second end opposed to the first end, the tapered second end configured to be inserted into and form a fluid-tight connection with the female fluid line connector, and
• a body longitudinal axis that extends between the first end and the tapered second end, and
• a locking collar, the locking collar comprising:
• an internal thread,
• a locking collar first end, and
• a locking collar second end opposed to the locking collar first end,
• wherein the locking collar first end comprises a plurality of resilient fingers positioned radially inward of an annular outer surface of the locking collar, the annular outer surface radially surrounding the plurality of resilient fingers, the plurality of resilient fingers tapered so as to extend radially inward at an angle with respect to the annular outer surface, the annular outer surface and the plurality of resilient fingers defining an annular space between one another wherein the plurality of resilient fingers can deflect, the locking collar connected to the body in a manner such that the plurality of resilient fingers of the locking collar can rotate about the body longitudinal axis, the locking collar second end configured to engage the outer surface of the female fluid line connector.

• and
• a locking collar comprising:
• a locking collar first end, and
• a locking collar second end opposed to the locking collar first end,
• wherein the locking collar first end is connected to the body in a manner such that the locking collar rotates about the body longitudinal axis, the locking collar including an internal thread that is configured to engage a corresponding thread provided on the outer surface of the female fluid line connector, the locking collar including through holes that are elongated in a direction parallel to the body longitudinal axis, the through holes extending between the interior surface of the locking collar and an exterior surface of the locking collar and through the internal thread, the locking collar first end comprising a first end face and the locking collar second end comprising a second end face, the through holes spaced from the first end face and the second end face so as not to extend through the first end face or the second end face.
