A method for bonding a tube (11) into a device (1) each of which is formed from a thermoplastic polymer. The device has first (2) and second (3) solid members in spaced-apart relationship to form a hollow cavity therebetween. At least one linear channel extends through each of said solid members in an aligned relationship, such that a tube (11) may be passed through in sliding engagement, including through the hallow cavity. Molten polymeric composition is injected into the hollow cavity (4) at a temperature lower than the melting point of the thermoplastic polymer so as to bond to the thermoplastic polymer and to the tube to form fluid-tight bonds therewith.
Procédé permettant de coller un tube (11) dans un dispositif (1), tous deux en polymère thermoplastique. Le dispositif comporte un premier (2) et un second (3) éléments solides disposés à distance l'un de l'autre de façon à former une cavité creuse entre eux. Au moins un canal linéaire traverse les deux éléments solides en alignement, dans lesquels on peut faire coulisser un tube (11) qui traverse également la cavité creuse. On injecte une composition polymère fondue dans la cavité creuse (4) à une température inférieure au point de fusion du polymère thermoplastique, de façon que la composition colle au polymère thermoplastique et au tube en formant des liaisons étanches aux fluides.
