The door has a locking sheet plate with a U-shape presenting long and short branches. The plate is arranged along a vertical lateral side of a framing sheet plate so that the long branch is fixed on the framing plate`s bottom and the short branch is placed on a side opposite to the lateral side to form a vertical housing in which a locking block (19) is slidingly inserted. The lateral side has holes (25, 26, 27) aligned with bolts (21, 22, 23) of the block, where a u-turn spring bolt (22) and a hole (26) have a larger section such that the bolt (22) is engaged only in its associated hole.
