    - une partie boîtier (2), qui est montée sur le support de contact (1) et présente une surface intérieure (22), qui, après le montage, entoure au moins en partie le ressort de serrage (4) ;
    - un dispositif d'ouverture de contact (5), en particulier dispositif d'ouverture de contact (5) allongé, lequel est à associer au ressort de serrage (4), est disposé au moins en partie entre cette surface intérieure (22) et le ressort de serrage (4) et, après le montage, est retenu de manière mobile entre deux positions ;
    où un premier mouvement est un mouvement de traction du dispositif d'ouverture de contact (5) le long de l'axe longitudinal (L), qui s'effectue dans la direction d'observation de l'extrémité arrière (32) de l'élément de contact (3), et un deuxième mouvement est un mouvement coulissant du dispositif d'ouverture de contact (5) le long de l'axe longitudinal (L), qui s'effectue dans la direction d'observation de l'extrémité avant (31) de l'élément de contact (3) ;
    où la surface intérieure (22) réalise une zone, dans laquelle, dans une première position du dispositif d'ouverture de contact (5), au moins une partie du dispositif d'ouverture de contact (5) est reçue, de sorte que le ressort de serrage (4) est libéré ;
    caractérisé en ce que
    - respectivement une surface (51) orientée au moins en partie transversalement par rapport à l'axe longitudinal (L) est réalisée sur cette surface intérieure (22) et sur une face (5a) du dispositif d'ouverture de contact (5) tournée vers cette surface intérieure (22) ;
    moyennant quoi, pour l'actionnement du ressort de serrage le long de la direction longitudinale, le dispositif d'ouverture de contact (5) peut être déplacé dans une deuxième position par un premier mouvement de glissement sur la surface (51) de cette surface intérieure (22) orientée transversalement par rapport à l'axe longitudinal (L) à partir de la première position, dans laquelle le ressort de serrage (4) est libéré, dans laquelle le dispositif d'ouverture de contact (5) comprime le ressort de serrage (4), de sorte que l'ouverture de serrage est ouverte pour l'insertion ou l'enlèvement de cette extrémité de fil libre, et le dispositif d'ouverture de contact (5), par un deuxième mouvement de glissement sur la surface (51) de cette surface intérieure (22) orientée transversalement par rapport à l'axe longitudinal (L), peut être ramené en direction de la première position bloquant l'ouverture de serrage.
  2. Connecteur électrique selon la revendication 1, dans lequel le ressort de serrage est un ressort de traction à cage, qui est disposé de manière serrée sur l'élément de contact.
  3. Connecteur électrique selon l'une quelconque des revendications 1 à 2, dans lequel le dispositif d'ouverture de contact (5) sur le deuxième côté long (5b) opposé au premier côté long (5a) du dispositif d'ouverture de contact (5) s'applique directement ou indirectement sur le ressort de serrage (4) et/ou le dispositif d'ouverture de contact (5) est réalisé d'une seule pièce.
