The element (A) has an O-ring seal (25) co-operating with an outer peripheral surface (13) of a male element (B) in a sealed manner, and an interface ring (27) moved in translation parallel to a fitting axis (X-X'). The seal and the ring are housed in a tubular body (21). The ring is axially moved by the element (B) during fitting of the element (B) in the element (A) from a position to another position. The ring is radially intercalated between the seal and the surface when the ring is in former position, and is axially offset with respect to the seal when the ring is in latter position. |
