Building structure equipment e.g. roof cladding panel, fixing hooking-case for e.g. female runner, of fixation device, has effort transmission unit cooperating with bottom to bring pushing unit in position with arms and to immobilize arms

摘要

The case (1) has two arms (23, 24) provided with hooking flanges (13, 14) cooperated with surfaces for maintaining the case in a hooking position under an action of an elastic return unit i.e. spiral spring, applied to one of the arms. A pushing unit (12) exerts an effort on the arms, and an effort transmission unit (15) is provided for maintaining the pushing unit at a distance of the arms and for cooperating with bottom to bring the pushing unit in a contact position with the arms and for immobilizing the arms.
