1. A connection device interconnecting two components made of plastics material, said two components comprising a first wall and a second wall, respectively, the first wall and the second wall having respective edges that, when the two components are assembled, are arranged one against the other,
wherein said connection device comprises:
at least one clip arranged on the first wall and extending beyond the edge of the first wall;
at least one first tooth and at least one second tooth arranged on the second wall and designed to be snap engaged by the at least one clip when the two components are in a pre-assembled state and in an assembled state, respectively, said at least one first tooth being closer than the at least one second tooth to the edge of the second wall such that, when pre-assembled, the two components are connected to one another by the edges of the first wall and of the second wall, said edges being spaced apart from one another, and said at least one first tooth having an inclined locking face for facilitating decoupling of the two components from the pre-assembled state, said inclined locking face facing towards the at least one second tooth; and
at least one centering pin arranged on one of said first wall and said second wall and extending beyond the edge thereof, and at least one centering seat arranged on the other of said first wall and said second wall and designed to receive the at least one centering pin,
wherein said at least one centering seat comprises a cylindrical sidewall and a frangible bottom wall which is broken through by the at least one centering pin when the two components are brought closer to one another than the two components are in the pre-assembled state, a plurality of perforations defined between a periphery of the bottom wall and the sidewall to enable the bottom wall to be broken away from the sidewall.
