1. A collapsible plastic storage and transport container comprising: a bottom part formed of a bottom plate and a bottom frame having frame sides, four collapsible sidewalls arranged in an articulated manner on the bottom part so as to be collapsible inwardly onto the bottom part, with two opposing first sidewalls being configured to be releasably locked with the two other opposing second sidewalls in corner regions of the container, at least two first recesses formed along each frame side and configured to receive connecting elements integrally formed on the first and the second sidewalls, the at least two first recesses having a bottom side, a back side, vertical walls and a front opening so as to be open inwardly and closed outwardly and having lateral boreholes which extend from the vertical walls parallel to the frame sides of the bottom part, at least one cover formed of two cover halves and connected on opposing sidewalls by way of cover hinges, a seal fixedly locking the cover with the container, lugs with an unobstructed front end extending laterally from the connecting elements parallel to bottom edges of the sidewalls, the lugs being rotatable with respect to the sidewalls about a pivot axis and configured for insertion into the lateral boreholes only when a major plane of the sidewalls is parallel to the bottom plate of the bottom part, so as to form in an assembled state a hinged connection between the bottom part and the sidewalls, and protrusions extending vertically from the bottom side along the back side of the first recesses, said protrusions engaging in an upright position of the four sidewalls with second recesses vertically formed in the connecting elements and preventing the lugs from being pushed into or pulled out of the boreholes when the sidewalls are in the upright position, wherein the first recesses in the frame sides are wider at an upper edge than in a lower region, wherein radially outwardly oriented cams on front ends of the lugs and wherein the boreholes have third radially inwardly arranged recesses which are oriented such that the lugs with the cams latch in the lateral boreholes only when the sidewalls are oriented parallel to the bottom part.
