A device (1) for the towing vehicle-trailer connection, comprising: - a base body (2) associable with a trailer and wherein is defined at least a first female coupling (3) and at least a second female coupling (6); - at least a first and a second male couplings (12, 13) associable with a towing vehicle of the trailer and insertable, respectively, within the first and second female couplings (3, 6); where the second male coupling (13) defines a first channel (31) for the transit of a working fluid and has a first closing element (32) of the first transit channel (31) movable between an opening configuration and a closing configuration, - valve means (17) able to put in communication and isolate between them the additional line (7) with the by-pass line (9), respectively; and where the valve means (17) comprise a first tubular element (26) movable between a release configuration and a fastening configuration, a second tubular element (28) defining a second channel (29) for the transit of the working fluid, there being provided a second closing element (30) of the second channel itself, the second tubular element (28) being movable with respect to the second closing element itself between a closing configuration and an opening configuration of said second transit channel (29); and where as a result of the insertion of the second male coupling (13) within the second female coupling (6), the second closing element (30) is able to contact the first closing element (32) to displace it from the closing configuration to the opening configuration, and the end of the second male coupling itself is able to contact the first tubular element (26) to displace it to the fastening configuration, the first tubular element (26) being able to drag in its displacement the second tubular element (28) to displace it to the relative opening configuration in order to place in communication the first and second transit channels (31, 29) together.
