The system detachably holds tunnel lights (15) at a cable ducting (1) which can be positioned by adjustment relative to the cable ducting. Elements (3, 4, 5) of each suspension (2) are adjustable and lockable relative to each other, in the three spatial directions at right angles to each other. The elements of each suspension consist of three angle sections. One limb (3b, 4b) of one angle section (3, 4) and one limb (4a, 5a) of the respective connecting angle section (4, 5), are connected by screws (8, 11) respectively. One limb and at least one elongated hole (9, 12) in the other limb penetrated by screws, are adjustable relative to each other. ADVANTAGE - Simplified installation work and reduced installation time. Uneven tunnel arches can be dealt with and at no increased cost.
