    • The device is used to fit a hot element (8) to a hollow body (1) including at least one cold fluid inlet pipe (2) and at least one fluid outlet pipe (3b), said hollow body (1) being made of a thermoplastic which cannot withstand the temperature of the hot element (8). The device includes an inlet adapter (9) of a single piece with the hollow body (1) and intended to surround said hot element (8) without contact, guide and retaining member (10) for keeping the hot element (8) out of contact with the inlet adapter (9) and retaining it inside the latter, seal (11) for sealing between the outer peripheral surface of the hot element (8) and the inner peripheral surface of the adapter (9), and means for causing at least some of the fluid penetrating the hollow body (1) to circulate through the space (14) lying between the adapter (9) and the hot element (8). Use especially for fitting an internal combustion engine exhaust gas recirculation pipe to an air intake manifold, made of thermoplastic, of said engine.
