1. An attachment part for a mechanical connection of a rear wall to a first and a second side wall, a base wall and a ceiling wall of an electrical switchgear cabinet comprising: two limbs formed in an L-shape, each limb including an inner face facing inward with respect to the L-shape and an outer face facing outward with respect to the L-shape such that the outer faces are disposed at a reflex angle; anda plurality of resilient tongues each integrally formed in one piece with the attachment part and extending, each resilient tongue extending outward from the outer face of a respective one of the limbs in a respective direction and including a latching lug projecting from the resilient tongue in a direction transverse to the direction of extension of the resilient tongue, wherein the attachment part can be attached to an inside of the rear wall at each one of four corners of the rear wall at a right angle with the rear wall, and wherein the first and the second side wall, the base wall and the ceiling wall are each firmly latchable to the latching lugs. 2. The attachment part as recited in claim 1, wherein each of the plurality of resilient tongues form a right angle with the outer face of the respective limb. 3. The attachment part as recited in claim 2, wherein the outer face of each of the two limbs each includes a groove running in a longitudinal direction of the attachment part, each groove having a first and a second side wall and a groove base, wherein each of the plurality of tongues are integrally formed on the first groove side wall in each groove. 4. The attachment part as recited in claim 3, wherein the first and the second groove side walls each include a plurality of cutouts disposed opposite the corner edge of one of the limbs or adjacent to an end edge of one of the limbs, wherein each of the plurality of resilient tongues are disposed in one of the plurality of cutouts, and wherein the plurality of tongues are integrally formed on a base of the groove. 5. An electrical switchgear cabinet comprising: a rear wall;a first and a second side wall each having a side edge and an inwardly bent second bent edge adjacent to the side edge;a base wall having a side edge and an inwardly bent second bent edge adjacent to the side edge;a ceiling wall having a side edge and an inwardly bent second bent edge adjacent to the side edge; andat least one attachment part for a mechanical connection of the rear wall to the first and the second side walls, the base wall and the ceiling wall, each attachment part having a plurality of resilient tongues each integrally formed in one piece with the at least one attachment part, each resilient tongue extending from the attachment part in a respective direction and including a latching lug projecting from the resilient tongue in a direction transverse to the direction of extension of the resilient tongue, wherein the attachment part is attached to an inside of the rear wall at each one of four corners of the rear wall at a right angle with the rear wall, and wherein the first and the second side, walls, the base wall and the ceiling wall are each firmly latched to the latching lugs, and wherein each one of the side edges adjoins a respective attachment part and each one of the second bent edges is latched so as to engage the latching lugs. 6. The electrical switchgear cabinet as recited in claim 5, wherein the at least one attachment part includes at least one longitudinally running groove and wherein each one of the second bent edges includes a further bent edge forming an L-shape, the further bent edge fitting into the at least one longitudinally running groove so as to form a U-shaped receiving groove at the second bent edge. 7. The electrical switchgear cabinet as recited in claim 6, further comprising an outer corner part for the at least one attachment part and having a strip projection, wherein a length of the outer corner part corresponds to a length of the at least one attachment part, and wherein the strip projection is insertable into the at least one longitudinally running groove so as to brace the first and the second side wall, the base wall and the ceiling wall. 8. The electrical switchgear cabinet as recited in claim 7, wherein the outer corner part includes two limbs disposed in a L-shape, and wherein the strip projection is fitted to an inner face of one of the two limbs. 9. The electrical switchgear cabinet as recited in claim 8, wherein the outer corner part includes soft-elastic sealing lips disposed on an edge of each of the two limbs and projecting in a direction of the two limbs and configured to seal against the first and the second side walls, the ceiling wall, and the base wall in an assembled state.
