In the present invention, there is disclosed a device for mutually connecting two parts (8) of road barrier of mass material, especially mass concrete wherein the device is disposed in an upper recess (1) being performed on a front connecting end of each barrier part (8). The device comprises an anchor and cover casings (3) that are arranged in mirror like manner on each side and that is fixedly anchored at their inner end in the barrier part (8) by means of an anchoring element (4) wherein the casings are provided at their outer ends with an opening with an internal thread. The device further comprises: an anchor plate (2) being attached to the anchor and cover casing (3) and bearing against inner wall of the recess (1) in the barrier part (8); a connecting anchor pin (5) being attached by means of a threaded connection to the casing (3) and being provided on one side with an internal thread and on the other side with a round head (9) with a central opening for a tool; a thread end half of two-part connecting head (6) having its inner surface provided with a recess of half-round shape corresponding to the outer shape of the round head (9), wherein the connecting head (6) half is passed over the corresponding round head (9) for mutual connection by means of the thread. There is also disclosed a method of connecting the two parts (8) of road barrier with each other. |
