Abstract: A male coupling for attaching to a female coupling in which rotation of the male coupling with respect to the female coupling is limited. In one embodiment, the male coupling has one or more tabs extending from a flange, the tabs limiting rotation when the male coupling is mated to a female coupling assembly for fluid conductors.

Abstract: A female coupling assembly for fluid conductors, having a coupling body, a latch plate, and a latch pin. The coupling body has a fluid pathway and a slot transverse to the fluid pathway. The latch plate is disposable in the slot, may be biased toward a locked position, and has a first lever portion and a second planar portion. The latch plate may be translated in the slot to an unlocked position by pressing the lever portion toward the coupling body. Upward translation of the latch plate may be limited by the latch pin. The latch plate may define a first generally central aperture and a second aperture opening into the first aperture. The central aperture may include a pair of raised radial edges flanking an upper portion of the second aperture, each radial edge flanked by an outboard notch.
