ABSTRACT:
A pin and wedge combination for connecting together adjoining lattice bridge panels (M) is characterised in that the pin (P) has a plurality of diametric slots (S) spaced along its axis and with ends which overlap in the general direction of the axis. Additionally, the wedge (W) is curved and resiliently deformable in a plane perpendicular to its depth whereby the wedge is insertable by deformation into any selected one of the slots (S) and thereafter resiliently engages spaced points of the sides of that slot so as to be self-retaining therein.
