A compound bolt (1) including a bolt (2) with a first end portion (21) and a second end portion (29) and a longitudinal axis (16), in which : - the bolt (2) is provided with a transverse bolt head (90) at its second end portion (29); - the bolt (2) includes a cylindrical portion (10) at its first end portion (21), with an external thread (12) for a nut (4) with a complementary internal thread (42); - the compound bolt (1) includes a safety device (6) arranged between the transverse bolt head (90) and the nut (4); and - the safety device (6) is provided, on the side facing the bolt head (90), with at least one locking body (32) projecting axially, the transverse bolt head (90) being arranged to be moved through a slot (34) in an object (8) from the front (80) of the object (8) and then be rotated around the longitudinal axis (16) until the bolt head (90) engages with the object (8) at the back (89) of the object (8), and the locking body (32) projecting, in an active position, through the slot (34) and out at the back (89) of the object (8) so that the transverse bolt head (90) is prevented from rotating out of its engagement; and the thread (12) of the first end portion (21) of the bolt (2) being provided with a deformation portion (5) so that the internal thread (42) of the nut (4) is non-complementary to the thread (12) in the deformation portion (5). A method for using the compound bolt (1) is described as well.
