The present invention relates to a device being used for connecting at least two railing elements (1) end (2) to end (2) by aid of at least two elongated bodies (3), which are provided with their ends (14) directed towards each other mainly in the longitudinal direction (23) of the railing elements (1), each of said elongated bodies (3) across its longitudinal direction (23) comprising at least one projection (4) intended to be inserted into upper portions (6) of said railing elements (1) into at least one downwardly directed opening (5) situated in these portions for connecting said railing elements (1) to each other, when they are placed on a ground (7) to protect personnel and road-users. Said ends (2) or projections (4) can be pressed towards each other or be released from each other by aid of at least one means (8), whereby said ends (14) or at least some part of the walls/edges (9) surrounding at least some portion of said projection (4), either can contact tight against each other with a minimized play or in an easy way can be released in an opposite direction for withdrawing the railing elements (1) from each other in their longitudinal direction. |
