Abstract: The invention relates to a collapsible transport and storage crate capable to be stacked. The sides (5) of the crate are provided with pins (13) sunk into connecting pieces (4) at the bottom of the crate. Upon folding down the sides they are lifted so that the pins (13) are pulled out of the connecting pieces (4) and are folded down hinged at them inward against the bottom. Thereby guide bosses (12) reach above the geometry of the folded-down crate and fix a crate located thereabove. In outfolded state tips (17) located on the upper edges of the sides can engage with pockets (15) located in the bottom of a crate thereabove and thereby fix said crate in lateral direction.
