an elastic connector (7) connected to the fastening flaps (2, 3) and interposed there for filling a space (6) between the structural elements (4, 5), and for allowing a relative movement of them; at least one profile (8) hooked to one of the fastening flaps (2, 3) from the side opposite the elastic connector (7), the profile (8) forming a channel elongated in the longitudinal direction; at least one illuminating element (9) positioned inside the channel. ## Claims ### Claim 1 An expansion joint (1) for building works, comprising: a first and a second fastening flap (2, 3) rigidly connectable to corresponding structural elements (4, 5) and elongated in a longitudinal direction; an elastic connector (7) connected to the fastening flaps (2, 3) and interposed there for filling a space (6) between the structural elements (4, 5), and for allowing a relative movement therebetween; at least one profile (8) fastened to one of the fastening flaps (2, 3) from the side opposite the elastic connector (7), the profile (8) forming a channel elongated in the longitudinal direction; and at least one illuminating element (9) positioned inside the channel. ### Claim 2 (depends on 1) The expansion joint according to claim 1, wherein: the fastening flaps (2, 3) and the elastic connector (7) form a flat surface; the at least one profile (8) forms a flat surface flush with the flat surface of the flaps (2, 3) and of the connector (7). ### Claim 3 (depends on 1) The expansion joint according to claim 1, further comprising: a transparent covering element (14) connected to the at least one profile (8) to close it above. ### Claim 4 (depends on 3) The expansion joint according to claim 3, wherein: the profile (8) has two undercuts (16) forming a housing positioned close to an upper opening of the profile (8) and shaped to receive the covering element (14). ### Claim 5 (depends on 1) The expansion joint according to claim 1, wherein: a side wall (15) of the at least one profile (8) and a corresponding side wall of the fastening flap (2, 3) are near to one another and shaped to match for forming a fitting. ### Claim 6 (depends on 5) The expansion joint according to claim 5, wherein: the side wall (15) of the at least one profile (8) has a protrusion (17) elongated longitudinally, inserted in a corresponding longitudinal groove (18) of the side wall (15) of the fastening flap (2, 3). ### Claim 7 (depends on 1) The expansion joint according to claim 1, wherein: each of the fastening flaps (2, 3) is a profile with an L-shaped cross-section having: a long side (19) which can be anchored to the structural element (4, 5), to be positioned parallel to an outer surface formed by the structural element; and a second side (20) having an end connected to the elastic connector (7) and hooked to the profile (8). ### Claim 8 (depends on 1) The expansion joint according to claim 1, further comprising: adhesive fixing means interposed between a side wall (15) of the at least one profile (8) and a corresponding side wall of the fastening flap (2 or 3). ### Claim 9 An illuminating body (22) for building works, comprising: a profile (8) elongated in a longitudinal direction, having a bottom wall (11) and two side walls (15) and forming a channel; at least one illuminating element (9) positioned inside the channel, a transparent covering element (14) inserted in a housing formed by the profile (8) close to an upper opening, by means of two undercuts (16) inside the profile (8), wherein one of the side walls (15) of the profile (8) comprises coupling means for fixing the profile (8) to a fastening flap (2 or 3) of an expansion joint designed to connect two structural elements (4, 5) separated by a space (6), the profile (8) being connectable to the expansion joint outside the space (6), wherein said at least one side wall (15) has a protrusion (17) elongated longitudinally, slidably insertable in a corresponding longitudinal groove (18) of a side wall of the fastening flap (2, 3), and wherein said side wall (15) has a flat outer face extending between the protrusion (17) and an upper end of the side wall (15) adjacent to the upper opening of the profile (8), wherein the protrusion (17) projects laterally in cantilever fashion from said flat outer face of the side wall (15) and defines a maximum lateral size of the profile (8), wherein said side wall (15) has a rib projecting from the side wall (15) in cantilever fashion towards the inside of the profile, to define one of said undercuts (16). ### Claim 10 A method for mounting an expansion joint (1) for building works, comprising the steps of: rigidly connecting a first and second fastening flap (2, 3) to a corresponding first and second structural element (4, 5) separated by a space (6), the fastening flaps (2, 3) and the space being (6) elongated in a longitudinal direction; interconnecting the fastening flaps (2, 3) by an elastic connector (7) interposed and positioned in the space (6) to allow a relative movement of the structural elements (4, 5); and fastening to at least one of the fastening flaps (2, 3), from the side opposite the elastic connector (7), a profile (8) forming a channel elongated in the longitudinal direction and containing at least one illuminating element (9). ### Claim 11 (depends on 10) The method according to claim 10, wherein: the fastening comprises a fitting of portions shaped to match of a side wall (15) of the profile (8) and a corresponding side wall of the fastening flap (2, 3). ### Claim 12 (depends on 10) The method according to claim 10, further comprising: a step for filling with epoxy resin a defined area between the profile (8) and a wall (19) of the fastening flap (2 or 3) positioned transversely to another wall (20) of the fastening flap (2 or 3) hooked to the profile (8).
