Process for pressing a weft thread in a jet loom, especially a loom air jet loom, tightening device and jet. They proposed a process and a tightening device for tightening of a weft thread in a jet loom. The wire of the weft thread crosses the initial segment (2) and the segment end (2.2) of a tube of mixture.The two segments are connected by a coupling opening (8) and are joined by a contramancal (9) with a first magnet retainer (11). In the initial segment (2.1) of the mixing tube is an actuator (6) in the form of a bellows of elastomer, which has a chamber (10).The camera (10) is connected via a supply conduit (20) to a valve (16), and is activated distinctly with compressed air. Through deformation of the actuator (6), a clamping element (7) with he Kingdom executes a tilting movement between the contramancal (9) and a part of RAM (19), which contains a second restraining element (12).The magnets of retention (11,12) lead to a precise and reliable clamping of the weft thread (3).
