Tightening tool comprising a driving part (4) forming the grip of the tool handle and a driven part (5) which includes a blade holder and the complementary distal part of the handle. The driving part and driven part have, in a first position of use, a common axis of rotation (X-X') and means (18, 19) for tilting the driving part (4) in relation to the driven part (5), comprising at least one tranverse pin secured to one of the two parts and movable in a longitudinal groove of the other part provided with a stop. Locking means (11, 26, 12, 29) are provided which adopt a positive locking position of the driving part (4) in a coaxial position relative to the driven part (5) by interlocking of both parts. Said parts can also adopt a position in which the tilting means (18, 19) are released through coaxial shifting of one part in relation to the other up to a predetermined spaced-apart position.
