A device for a connection link between two structural members (1, 2), e.g., two door leaves, a door and door frame, table leaves or similar, where at each end of the adjacent edge portions of the structural members a pair of coupling members (14, 15) are provided which have coordinated movement by means of tooth-rimmed segments (23, 24) on each of the coupling members, means (3) being provided to hold the centres of curvature of said tooth-rimmed segments at a fixed distance from one another, and made of an extruded profile body having a smooth, closed periphery, and which extends between two pairs of coupling members and is designed to fill the space between said edge portions (4, 5) of the structural members. The profile body in cross section has a rounded part (6, 7) at each end and a waist which has a smaller cross section than the rounded part, and the edge portions (4, 5) are each made with a complementary, rounded part which spans an arc which is equal to or less than said rounded part of the profile body, preferably in the range of 120 DEG -210 DEG , more preferably 165 DEG . |
