A formwork cartridge (10a) which, together with further identical formwork cartridges (10b, 10c and so forth), besides a formwork plate (23a), comprise a framework consisting of two parallel uprights (11a) connected through intermediate, lateral transoms (12a), wherein the outer end faces (12a') of the transoms (12a) rest against the neighbouring side face (11a') of the adjacent upright (11a), and wherein the connection between uprights and transoms is established in the areas of said faces (12a' and 11a') resting against each other, by means of fixing means such as nails, fishiing plates (13a) and/or similar fixing means. In order to establish a strong connection between uprights and transoms, requiring a minimum of securing measures to be taken by means of said fixing means, said end faces (12a') of the transoms (12a) and said side faces (11a') of the uprights (11a), said side faces resting against the transom end faces, are chamfered such that they slope forming an acute angle with imaginary vertical planes (II-II) perpendicular to respective formwork plate (23a). The strengthening of the connections between uprights (11a) and transoms (12a) enables a reduction in upright and transom dimensions, maintening the same strength properties as known formwork cartridges having the same external measures.
