The assembly wrench consists of a carrying block (1) equipped with two opposing cylindrical arms (12); the carrying block (1) has a rectangular hollow (2), the shorter side of which is perpendicular to the longitudinal axis of the cylindrical arm (12) and in the middle of its longer side (3) there is a shaped channel (15). Each cylindrical arm (12) has a central passage hole with a thread the longitudinal axis of which is identical to the longitudinal axis of the cylindrical arm (12). In each central through-hole there is safety bolt (6) one end of which is equipped with a cylindrical head and the other end has a rounded supporting pin (8) entering the rectangular hollow (2). There is a rotary handle (7) on each cylindrical arm (12) inside of which there is a cylindrical hollow for fixing the cylindrical head of the safety bolt (6). The diameter of the cylindrical hollow of the handle (7) is greater than the external diameter of the cylindrical arm (12).<IMAGE>
