Abstract: The invention relates to a folding trestle having a folded position and a deployed position, said trestle comprising: a crossbeam having a longitudinal dimension and a transverse dimension that define a bottom face; first and second pairs of legs; and hinge mechanisms enabling the legs of each of the pairs of legs to be spaced apart from each other when the trestle is in the deployed position, and to extend against each other when the trestle is in the folded position, the hinge mechanisms also enabling each of the pairs of legs to pivot about a respective axis that is transverse to the crossbeam so that, in the folded position, the pairs of legs extend under said bottom face of the crossbeam. The invention is characterized in that the trestle further comprises a first locking device connecting one side of one of the legs of at least one of the pairs of legs to the crossbeam in order to lock said pair of legs in the deployed position relative to the crossbeam.
