Abstract
A frangible male coupling component for sealingly coupling a conduit to a fluid delivery device of the type having a female coupling component with a threaded axial passage therethrough and an internal camming surface in the passage. The male coupling component has an integral tubular body of one-piece construction sized to coaxially receive the conduit to be coupled. The tubular body has an axial inner ferrule portion engageable with the camming surface, an axial outer screw portion, and an annular frangible portion integrally connecting the ferrule and screw portions. The frangible portion is designed to break on rotation of the screw portion when the ferrule portion is in engagement with the camming surface, with continued rotation of the screw portion in the first direction effecting relative axial movement of the screw portion relative to the ferrule portion to a point where the screw portion presses the ferrule portion against the internal camming surface, thereby causing the ferrule portion to deform radially inwardly to form a seal around the conduit. The frangible portion is configured to break into separate parts attached to the screw and ferrule portions, the parts being engageable with one another to inhibit separation of the screw and ferrule portions in the event the male coupling component is removed from the female coupling component.
