Abstract
A coupling device intended to be applied on a vehicle, and which includes an attachment portion and a coupling portion, one of said portions including a tube shaped female element and the other one a longitudinal male element intended to be received in the female element. A movable piston, sidewardly spring biased towards the female element, is able to be introduced a side recess in the male element, the piston being kept pressed into the side recess by an abutment element in a first mutual position of engagement between the piston and the abutment element. The abutment element, being sidewardly engaging into the path of movement of the piston, is arranged so as to be able to be brought essentially in the longitudinal direction of the piston while bringing the piston to a mutual second position of engagement between the abutment element and the piston, in which the abutment element keeps the piston caught, against the action of the spring bias, essentially outside the path of movement of the male element in the female element.
