摘要

The angle adjustable fixed and releasable connection of two light construction profiles (1,2) has a threaded preformed piece (3,4) for each profile and into which is screwed a spherical head (8) on one side and a spherical socket (9) on the other side. The spherical head and spherical socket are locked in their axial position by locknuts (5,6). The connection between the spherical head and spherical socket, and therefore of the light construction profiles, is created by the screwing of a union nut (10) onto the male thread (17) of the spherical head.
