An attachment system for cables (7), in particular for wind turbines, has a base body (1, 3) securable to a support structure and forming cable bushings (5) with openings for cables (7). The openings can be closed by a cover (17) applying retaining forces to the cables (7). The cable bushings (5) on the base body (1, 3) are arranged at least over part of a ring, with an outside opening. The cover (17) has retaining bodies lockable to the base body (1, 3) for preliminary fixing of the cables (7) inserted into the cable bushings (5) and a tightening strap (17) encompassing the base body (1, 3) and applying retaining forces to the cables (7) via the retaining bodies.
