Abstract: Disclosed are chromatography systems employing a releasable coupling 100 for holding a fluid tubing to a spigot, the coupling comprising: a cylindrical inner component 110 for accepting a fluid tubing 30, said inner component including a resiliently deflectable portion 118 arranged to urge an outer surface of the tubing toward a spigot; and a cylindrical collar 130 having and internal through-aperture 132 for slideably accepting the inner component, the aperture and resilient portion having complementary surface formations which in a first position of the collar mounted to the inner component provide for said resilient deflection in use, and which in a second different position do not cause said deflection, the coupling being characterized in that the collar comprises a collar flange 134 extending outwardly away from the aperture of a size allowing manual manipulation of the collar between the first and second positions. Chromatography systems employing said couplings is disclosed also.
