Claim:
A road safety barrier comprising: an upright ( 11 ) comprising two separate lateral flanks ( 12 a , 12 b ) joined along a center plane of the upright, one of the lateral flanks ( 12 ) of the two separate lateral flanks ( 12 a , 12 b ) in reflection symmetry to an other lateral flank of the two separate lateral flanks ( 12 a , 12 b ), the one of the lateral flanks comprising: a bottom wall ( 21 ) arranged in a horizontal plane being of greater width at a front edge than a back edge, a back wall ( 35 ) arranged on a vertical plane, a bottom edge of the back wall connecting to the back edge of the bottom wall, an inside edge of the back wall connecting to an inside edge of the back wall of the other lateral flank ( 12 ) of the two separate lateral flanks ( 12 , 12 ), and an outer wall ( 13 ) arranged on a vertical plane, a back edge of the outer wall connecting to an outer edge of the back wall ( 35 ), and a bottom edge of the outer wall connecting to an outer edge of the bottom wall ( 21 ), a front edge of the outer wall faces a roadway forming an acute angle relative to the bottom edge of the outer wall; a skirt attached along the front edge of the outer wall, said skirt conforming to a shape of the front edge of the outer wall; and a guide upon which an anchoring means is placed to mate each of the two separate lateral flanks together, said anchoring means comprises a dowel to anchor said upright to a roadway, said guide comprises an inner wall arranged on a vertical plane of each of the two separate lateral flanks and attached to an inner edge of the bottom wall substantially orthogonal to the ground and distanced by a space for passage of said dowel, wherein said anchoring means comprises a slider to slide on a top surface of an inner wall of each of the two separate lateral flanks.
