A clamp connector for clamping together connecting pieces (5) on pipelines, having two clamping ring parts (1,3) which are connected at one end by means of a joint arrangement (11) and which are pivotable about said joint arrangement (11) between spread positions and clamping positions in which said clamping ring parts (1,3) are situated close to one another, and having a clamping device which is situated at the opposite end of the clamping ring parts (1,3) from the joint arrangement (11), which clamping device has a clamping screw (19) which can be pivoted from an active position, in which said clamping screw (19) interacts with the clamping ring parts (1,3) in order to generate a clamping force which presses said clamping ring parts (1, 3) into the clamping positions, and a release position in which said clamping screw (19) is pivoted away from said clamping positions and in which the clamping ring parts (1,3) are released, is characterized in that the clamping device has a locking device (25, 27) which, in the active state thereof, prevents the clamping screw (19) from being pivoted out into the release position and which, as a function of the spread of the clamping ring parts (1,3), passes through a predefined opening angle from the active state into a release state in which the clamping screw (19) can be pivoted out.
L'invention concerne un dispositif de serrage pour fixer par serrage des tubulures de raccordement (5) à des conduites, avec deux parties de bague de serrage (1, 3) qui sont reliées à une extrémité par un dispositif d'articulation (11) et peuvent basculer autour de celui-ci entre des positions écartées et des positions de serrage rapprochées l'une de l'autre, et avec un dispositif de serrage se trouvant à l'extrémité des parties de bague de serrage (1, 3) opposée au dispositif d'articulation (11) et comprenant une vis de serrage (19) qui peut être basculée d'une position active dans laquelle elle coopère avec les parties de bague de serrage (1, 3) pour produire une force de serrage poussant celles-ci dans les positions de serrage et une position de libération rabattue dans laquelle les parties de bague de serrage (1, 3) sont libérées. Le dispositif de serrage est caractérisé en ce qu'il présente un dispositif de blocage (25, 27) qui, dans son état actif, empêche de rabattre la vis de serrage (19) dans la position de libération et qui, en fonction de l'écartement des parties de bague de serrage (1, 3) d'un angle d'ouverture prédéfini, passe de l'état actif dans un état de libération permettant de rabattre la vis de serrage (19).
