<p>The invention relates to a non-reusable hose-clip, intended to ensure for example the connection of two tubular members. The invention also relates to a tool for tightening the clip. The clip is composed of a band forming a loop comprising a free end (2). It is characterized by the fact that in the vicinity of the other end it comprises locking means (4) which are self-tightening due to wedging of the free end. These means are preferably constituted by a casing (8) of convergent shape and a wedge (17) of complementary shape. Possibly, spring means (24) restore the wedge to the locked position. Also, wedging may be reinforced by the engagement of complementary teeth. Also, in the vicinity of the terminal part of its free end (2), the clip according to the present invention comprises means facilitating calibrated tightening of the latter. According to one embodiment, these means comprise an aperture (7), possibly a flange (6) by which the swinging head of a pulling tool engages the band. According to another embodiment, these means comprise a calibrated deformation in the free end (2) which a pulling tool "rolls".</p> |
