Connector coupling assembly

A coupler comprising:

• a first connector having a first end, a second end opposite the first end, and a first valve disposed between the first end and the second end;
• a second connector having a mating portion, a connecting portion opposite the mating portion, and a second valve disposed at least partially within the mating portion;
• and
• a collar having:
• a body detachably coupled to the mating portion of the second connector;
• and
• a releasing portion disposed opposite the body, comprising a slot, and configured to flex radially inward to close the slot,
• wherein, when the slot is open, the slot receives at least a portion of the first connector to detachably couple the first connector to the collar and the second connector such that the second end of the first connector is disposed within the second connector,
• wherein the releasing portion flexes radially inward to close the slot when the first connector is decoupled from the collar and the second connector such that the first connector is prevented from re-coupling to the collar.

A coupler comprising:

• a first connector having a first end, a second end opposite the first end, a central axis extending through at least the first end and the second end, a body disposed between the first end and the second end, and a first valve disposed proximate the second end, the body having an interior space housing the first valve and a biasing element coupled to the first valve;
• a second connector having a threaded mating portion, a connecting portion opposite the mating portion, a second valve disposed within the mating portion, and a pin disposed at least partially within the mating portion;
• and
• a collar having a releasing portion detachably coupled to the first connector and a body threadably coupled to the mating portion of the second connector, the releasing portion having a slot that opens and longitudinally extends through the releasing portion and receives at least a portion of the first connector when the releasing portion is coupled to the first connector,
• wherein the collar is configured to couple the first connector to the second connector such that at least the second end of the first connector is disposed within the second connector,
• wherein the first connector is configured to decouple from the collar and the second connector in response to a pullout force exceeding a predetermined threshold force,
• wherein the slot is configured to close when the first connector decouples from the collar,
• wherein the first connector is prevented from re-coupling to the second connector and the collar when the slot is closed,
• wherein the central axis extends through the first connector, the collar, and the second connector when the collar is coupled to the first connector and the second connector.
