Abstract
Screwing tool (1) having a grip (2) and a shank (3), which is received removably in a cavity (4) open toward an end of the grip (2) and which at its free end has an actuating portion (5). The shank (3) is retained in a position of use such that it is fixed in terms of rotation on the grip, to avoid sliding in the axial direction, by a retaining element (14) associated with the grip (2). The retaining element (14) can be displaced into a removal position by displacement of an actuating member (6) in order for the shank to be removed from the grip (2). In a storage position, a large part of the shank (3) is located in the cavity (4), where it is held by a holding element (H). The holding element (H) is releasable, so that part of the shank (3) can be moved out.
