ABSTRACT:
An apparatus for connecting first and second conduits having first and second bores, respectively, to provide communication between the first and second bores. The apparatus includes a base attached to the first conduit and a cap attached to the base. A follower is slidably disposed in the cap and is provided with a passageway, the second conduit extending through the passageway. A ferrule is received on the second conduit, the ferrule having a first end and a second end. The follower is biased against the first end of the ferrule. The first bore in the first conduit has a frustoconical surface which defines a receiving formation for the ferrule, the ferrule having a portion which is circular when viewed in transverse cross section. When the second end of the ferrule is urged in the receiving formation by the action of the biasing spring, the ferrule engages the frustoconical surface defining the receiving formation in substantially line contact.
