Abstract

L'invention porte sur un accouplement (1) destiné à accoupler un accessoire (5) à un bras d'une machine. L'accouplement comprend : une structure (6) ayant des première et seconde mâchoires (25, 26) ; des moyens de retenue (21) servant à verrouiller une première broche (35) d'un accessoire dans la première mâchoire ; et des moyens d'actionnement (12, 13, 14) servant à déplacer les moyens de retenue entre une première position, dans laquelle ils verrouillent ladite première broche dans ladite mâchoire, et une seconde position dans laquelle ils ne verrouillent pas ladite première broche dans ladite première mâchoire. L'accouplement comprend en outre un dispositif de verrouillage (39, 40, 41, 42, 43, 44, 45, 46) servant à empêcher les moyens d'actionnement d'amener les moyens de retenue à la seconde position sauf si un axe longitudinal de l'accouplement est disposé dans une direction appropriée pour que cela se produise.
