The invention relates to a fixing system for pyrotechnic launch tubes. More specifically, the invention relates to pyrotechnic launch tubes (1) comprisi ng a cylindrical body which contains both the pyrotechnic materials or objects (3) and the powder (5). According to the invention, the lower base of each cylinder (1) is provided with a series of pins (6) which define a radially- deformable neck. Harpoons (7), which are disposed at the end of each of said pins (6), are used to attach the tubes by means of pressure to a fixing element (11-11'), which can be fixed to the frame of the tubes or integrated as single piece into said frame. The aforementioned fixing element is provid ed with: an external rigid neck (14) having a stepped configuration which is us ed to fix the harpoons (7); and a cylindrical, axial core (10) which perforates the base of the cylinder (1) and which is dimensioned to house the igniter (12) and the corresponding cable (13) therein such that they are perfectly protected against any possible ambient moisture.
