A pipe (1) conveying molten material upwards from a pressurized receptacle into the mould (17) of a low pressure diecasting machine (2), positioned on and supported by the selfsame receptacle, is secured in a fluid-tight fit by an adjustable coupling device; the pipe (1) extends through the top wall (4) of the receptacle and comprises a body (5) of which one end extends into the receptacle so as to pick up the molten material and the other terminates in a head (6), located externally of the receptacle and tightened together with a seal (28) against the mould (17). The outer surface (10) of the pipe (1) presents at least one substantially frustoconical portion (13) matched to the surfaces (15) of three wedges (12), disposed circumferentially around the pipe and mounted on slide ways (20), which can be directed by suitable actuators (16) from an at-rest position to an operating position in which the pipe is subjected to an axial force and distanced from the receptacle, and the head (6) clamped together with the seal (28) against the machine (2).
