<p>Purge branch coupling for a main flexible hose (3), reinforced or not, sheathed or unsheathed, of the type having the shape of a tubular insert (1) which is intended to co-operate with a closure piece of its proximal extremity and which is integral with the main hose (3) by moulding coating of a splicing material (8), particularly comprised of plastic or elastomer material. According to this invention, the tubular insert (1) forming the purge branch coupling comprises a plurality of openings (9) provided in its tubular wall so that the coating of said splicing material (8), which penetrates into said openings (9) during moulding, establishes linking bridges (10) between the portions (8a, 8b) of said coating (8) which envelope the insert (1), thus providing for the holding in position of said insert (1). Application for couplings in lines of water, air and fuel circuits in motor vehicles.</p> |
