Cloning of the complete gene for pig PIT-1 and analysis of PIT-1 protein function

A hose coupling shroud for enclosing and securing coupled ends of a pair of hoses, particular those of the type used to convey an abrasive media under high pressure. The shroud has tapered portions at oppositely-disposed ends thereof, openings at the oppositely-disposed ends for receiving the hoses, and vents to allow excess pressure and media to be released from the hose coupling shroud in the event of a coupling failure. Radially-projecting ribs within the tapered portions secure the coupled ends of the hoses within the shroud in the event of coupling failure, and form a pair of sealing barriers between the coupled ends and the openings at the oppositely-disposed ends of the shroud. The tapered portions reduce the likelihood that the hose coupling shroud will become snagged on an object as the hoses are pulled through a work environment.
