Abstract
This invention relates to a sealing device ensuring lateral tightness of a weir gate with respect to the corresponding lock wall, of the type comprising a lip disposed over the whole length of each lateral face of the gate and a rounded rib extending the leading face of said gate, wherein the rounded rib projects transversely beyond the plane of the lock wall, so that its periphery, which takes a circular form, comes into abutment against the lateral face of a cylindrical chamber made in the lock wall. In this way, the displacements of the gate do not affect tightness.
