Abstract: A lashing device integrated in truck superstructure walls, in particular plywood panels, has a plurality of lashing cups (2) arranged next to each other in horizontal rows. Each lashing cup (2) has a truncated cone shape which tapers towards the cup bottom (2a), can be form-fitted into corresponding recesses of the superstructure walls and fixed therein with an adhesive. Each lashing cup (2) has a strip (5) located inside and at the center of the lashing cup (2), and an outer flange (8) that extends parallel to the cup bottom (2a) around the open cup side. The strip (5) in each lashing cup (2) matches an end coupling piece (9) of a locking bar that can be inserted between two opposite lashing cups (5).
