Zusammenfassung:	The invention relates to a gas injection element (10) for a system for distributing as gas inside a chamber of a fluid catalytic cracking unit. This injection element comprises a passage (14) passing right through it in a longitudinal direction (X), and -a metallic internal element (20) of which an internal surface (22) defines part of the through-passage (14) passing through in a longitudinal direction (X), -a hollow metal sleeve (30) accepting one end (20a) of the internal element (20) and attached thereto, -a hollow metal support (40) having an internal surface (42) defining the remainder of the through-passage passing through in the longitudinal direction (X), the said sleeve also being attached to one end of the support (40).
