A process of manufacture for and the article which comprises a connecting and/or branching of flexible hoses is characterized in that an outer covering element (6) provides a compressive action of the walls of the ends of the flexible hoses (5) onto a rigid inner pipe (1). The outer covering element (6), may comprise a polymer of which the contraction during cooling of the polymer is at least equal to 1% of its original diameter. The invention is adapted for use in fluid circuits between different parts or engine units in a vehicle.

A connecting and/or branching device for use in a fluid system which comprises: a rigid inner pipe; at least one flexible hose having a wall with inner and outer surfaces, and an end portion of the inner surface extending over an outer surface of said rigid inner pipe; and an outer covering means that has an internal diameter which surrounds the end portion of said at least one flexible hose, said outer covering means being made of a non-elastic polymer which is injection moulded about said end portion and contracts during cooling in place on the hose outer surface following thermal heating to higher than ambient temperature when formed on said flexible hose, the contraction being at least equal to 1% of the covering means internal diameter to provide a compressive action on a hose end of said at least one flexible hose that is fitted onto the rigid inner pipe, said compressive action being achieved between the outer covering means and the rigid inner pipe to provide a mechanical bonding between the at least one flexible hose and the rigid inner pipe.
