The cap (10) as claimed in claim 4, characterized in that the interior tubular bearing surface (40) of the cover (26) includes at least one peg (46) that constitutes the first, second and third members projecting radially toward the interior of the cover (26). 6. The cap (10) as claimed in claim 4, characterized in that the periphery of the base (16) receives a ring (48) that carries at least one upper abutment (36) and one leaf spring (38). 7. The cap (10) as claimed in claim 5, wherein the periphery of the base (16) receives a ring (48) that carries at least one upper abutment (36) and one leaf spring (38); and wherein the interior tubular bearing surface (40) of the cover (26) includes at least two diametrically opposite pegs (46), the base (16) includes two diametrically opposite ramps (42) and the ring (48) includes two upper abutments (36) and two leaf springs (38) diametrically opposite in pairs. 8.
