The angular connection means (10) for tubular protection bars (12.1, 12.2) or handrails, comprises: two elements (14.1, 14.2) each comprising an expandable part (13.1, 13.2) insertable, before expansion, into the open end of a relative bar (12.1, 12.2), the expandable element (14.1, 14.2) remaining locked within the bar (12.1, 12.2) following expansion, each expandable element (14.1, 14.2) also comprising a part (22.1, 22.2) intended to project from the end of the relative bar (12.1, 12.2) and comprising a coaxial head; an angular connection element (24) comprising two superposable angular half-elements (24s, 24i), each provided with corresponding half-seats (34.1, 34.2) adapted to receive the head (20.1, 20.2) of each of the two expandable elements (14.1, 14.2) to establish a connection between these latter when the two half-elements (24s, 24i) are superposed and joined together by connection means (26, 28). The head (22.1, 22.2) of each of the two expandable elements (14.1, 14.2) is a spherical head, the half-seats (34.1, 34.2) having a spherical surface shape (34.1, 34.2) mateable with the spherical surface of the relative spherical head (22.1, 22.2) to form a ball joint.
