A bayonet connector and assembly. The bayonet connector has a threaded protrusion or connector coupled to a bayonet protrusion with a body and a plurality of nubs spaced from the end of the body and spaced radially from each other. There is a screw head and a radial lip that trap an elastic washer. The plurality of nubs are asymmetric and have noses and tails with the noses having shallower tapers than the tails such that the nose presents a more gradual engagement with the traps of the bayonet receiver. The bayonet receiver receives the body and plurality of nubs of the bayonet protrusion axially and on a rotational action to receive and secure the plurality nubs nose-first.
