An intake manifold with integrated canister circuit for a supercharged internal combustion engine. The intake manifold includes a tubular body in which a plenum is defined. A sorting chamber is in a wall of the tubular body. A canister solenoid valve is arranged in the sorting chamber and is adapted to adjust the introduction of gasoline vapors into the sorting chamber itself. A first pipe in the wall of the tubular body puts the sorting chamber into communication with the plenum, and defines a first branch of a recovery pipe. A one-way valve is arranged in the sorting chamber at the first pipe. A second pipe in the wall of the tubular body puts the sorting chamber into communication with the intake pipe upstream of a compressor, and defines an initial portion of a second branch of the recovery pipe.

A lock coupling between two mechanical components and presenting: at least one pair of coupling elements, each of which presents an 'L'-shape and protrudes from a first mechanical component; and at least one pair of tracks, each of which is made through a second mechanical component, presents the shape of an arc of circumference, ends with a flared inlet opening, and is engaged in use by a coupling element; each track presents a dimension so as to prevent the axial removal of the coupling element along its entire length except for an inlet opening at which the coupling element can be axially removed.
