Kind Code:

Abstract:
The present invention relates to a device for connecting protective blocks temporarily provided to be adjacent to each other on a road, the device comprising: a base plate (20) formed in an inverted U-shape so as to face a fastening hole (12) of the protective block (10); a main link (30) connected between the lower ends of the base plates (20) that are coupled to the adjacent protective blocks (10); and a sub link (40) connected between the upper ends of the base plates (20) that are coupled to the adjacent protective blocks (10). Therefore, connection simplicity and convenience are ensured so as to simultaneously satisfy relevant regulations and improve productivity, while removing the concern of weakened strength when the protective blocks are temporally applied for construction, modification, repair, traffic control and the like of a road.
