<p>The invention concerns an internal device for reducing the number of loose components (compression washer, lock or snap ring, optionally joint or other components) mainly related to joint compression piping connections, removable and reusable, in all materials and shapes. The invention concerns a single-piece compression device for fixing joint compression connections on pipes, with time-saving for assembling (or disassembling), adapted, even improved, reliability and without risk of losing internal components while preserving the removable character and integrity of the pipe. It consists of a single-piece compression ring (0) which assembles, directly or indirectly into a single part, which moreover is of the clip-on type, a zone (5), in the nut (8): the compression element, the zone (1) with its rigid zone (2) and the clamping element (3) with its slot(s) (4)- and in a second phase (optional) the joint (9) can be secured to the ring (0) zone (1). The device in its nut connects the connection body (10) and the tube (11). There are various embodiments with different shapes of rings. It is possible to check the clamping visually by observing the closure of the exposed slot(s) of the nut (8).</p> |
