ABSTRACT:
The present invention relates to means for connecting two fixed or floating bridge elements together. A first bridge element comprises at least two retractable studs (1, 2) oriented obliquely with respect to the surface of the element, one on the intrados and the other on the extrados, so as to cooperate with a recess (3', 4') either of the extrados or of the intrados of a second bridge element. This invention may be used to assemble all types of bridges.
