A coupler for making a detachable bayonet connection between two sections of a flow path. The coupler includes male and female bayonet hub members that detachably connect the flow path sections. In one aspect of the invention, the coupler includes an internal vapor shielding flow path defined within the coupler by the interconnection of the hub members that operates to intercept and remove heat entering the coupler from the external environment. In this regard, the internal vapor shielding flow path may include at least one valve to vent at least a portion of the vapor shielding material external to the coupler from the vapor shielding flow path.
