Abstract

L'invention concerne un dispositif de fixation (5) mis en œuvre en particulier dans un dispositif d'entraînement électromagnétique (2), permettant de fixer un premier composant principal (3) dans une position d'utilisation dans laquelle il est monté sur un tenon de support (22) d'un deuxième composant principal (4). La fixation intervient par un assemblage par encliquetage qui peut être réalisé au moyen d'une pince ressort (33) comprenant deux branches ressort (48) espacées l'une de l'autre et reliées l'une à l'autre par un élément de liaison (49) présentant une ouverture (53). A des fins d'encliquetage, les deux branches ressort (48) peuvent être écartées l'une par rapport à l'autre, le tenon de support (22) faisant saillie entre ces deux branches ressort (48), à travers l'ouverture (53) de l'élément de liaison (49). La mise en œuvre de dimensions compactes est ainsi réalisable. Cette invention concerne en outre un ensemble électrovanne (1) équipé desdits moyens.
