A formwork for civil engineering parts, in particular cable junction boxes, with formwork frames to be arranged inside and outside on wall parts, has formwork frame parts (35-42), designed in the form of boards, and clamps (43-50), which can be fitted from above on the outside of the outer formwork frame parts and on the inside of the inner formwork frame parts and hold the latter on the wall parts. These clamps (43-50) comprise U-shaped moulded parts with legs which are resilient with respect to each other and can be pushed onto the outside of the outer formwork frame parts and the inside of the inner formwork frame parts or else are held in an articulated manner on the formwork frame parts. The outer frame of the formwork has outer corner stabilisers (77) as angle pieces and, at the same time, holders for adjustable bearers of an upper covering component. The inner formwork parts (35-38) have in the region of their central width inwardly open pockets (61-64), which are at a distance from one another in the longitudinal direction and, tapering obliquely from the upper edge of the central width towards the lower edge, end at a distance from the lower edge on the inside. <IMAGE>
