Couplers are described herein. A coupler includes a coupler body, a plurality of first retaining fingers, and a plurality of second retaining fingers. The coupler body includes a first end and a second end, and defining a cavity, the cavity configured to receive a first connector and a second connector. The plurality of first retaining fingers are configured to engage against a collar of the first connector to prevent axial motion of the first connector relative to the coupler. The plurality of second retaining fingers are configured to engage against a shoulder of the second connector with a retention force, and release the second connector by radially expanding in response to a pullout force exerted on the second connector exceeding the retention force.

Material transfer interfaces for space vehicles, and associated systems and methods are disclosed. A representative system includes a first coupler configured to be carried by a first space vehicle, and a first valve device carried by the first coupler. The system further includes a second coupler configured to be carried by a second space vehicle and a second valve device carried by the second coupler. The first coupler includes rotatable and translatable latch arms positioned to engage with and connect to the second coupler. The first valve device incudes a moveable probe that is insertable into the second valve device when the latch arms of the first coupler are connected to the second coupler to transfer fluid between the first and second valve devices.

A quick connector includes a male base and a female base, wherein the male base has a first tube body, an annular clamping groove arranged outside the first tube body, a first flow channel axially penetrating through the first tube body, a plug body slidably arranged in the first flow channel, and an elastic member for pushing the plug body to close the first flow channel. The female base includes a second tube body, a second flow channel which axially penetrates through the second tube body and into which the first tube body is inserted, an annular fastener provided in the second flow channel, and a push rod fixed on the second flow channel and oriented towards the plug body.

Provided is a connector including: a plug to be attached to an opening of a liquid storing container and attached to an inner peripheral surface of the opening; a key ring to be attached to an outer peripheral surface of the opening extending along an axial line and including a key hole portion disposed at an outside of the outer peripheral surface with respect to the axial line; and a socket to be detachably attached to the plug and including a key rod portion to be engaged with the key hole portion. The plug and the socket are coupled together in a state where the key hole portion and the key rod portion are engaged with each other.
