Abstract

L'invention concerne un accouplement par emboîtement verrouillable pour assembler deux éléments (2, 62). Il est constitué d'un corps d'accouplement (4, 4') qui peut être fixé sur un des deux éléments, d'une broche d'accouplement (6, 6') qui peut être fixée sur l'autre élément, et d'un bouton de déverrouillage (8,8'). Le corps d'accouplement (4, 4') et la broche d'accouplement (6, 6') peuvent être accouplés par un assemblage par enclenchement (R, R') qui est enclenché par un mouvement relatif prédéfini entre le corps d'accouplement (4, 4') et la broche d'accouplement (6, 6'), afin d'empêcher un mouvement relatif en sens contraires entre le corps d'accouplement (4, 4') et la broche d'accouplement (6, 6') et de verrouiller ainsi l'accouplement par emboîtement. Le bouton de déverrouillage (8,8') peut être déplacé d'une position neutre dans une position de déverrouillage, afin de défaire l'assemblage par enclenchement (R, R') et de déverrouiller ainsi l'accouplement par emboîtement.
