The invention concerns a road trailer whose frame consists of profiles having a fin to support the floor and grooves on their upper and lower faces able to retain in rotation bolt heads and the lower edges of sidewalls ( 10 ). The side members and cross bars are joined by corner pieces which have a vertical orifice to receive the lower end of a post ( 9 ) comprising orthogonal grooves housing the side edges of the sidewalls (10). The corner pieces ( 30 ) have two perpendicular arms respectively fitted into the adjacent ends of profiles forming the frame. Mounting of the elements requires little tooling.
