The safety device for pipes fitting comprises first valvular means (10) suitable to be connected to a first pipe, second valvular means (20) suitable to be connected to a second pipe, a control device (30) suitable to perform the opening and closing of the first and second valvular means (10, 20) and a connection device (46) suitable to connect the first valvular means (10) to the second valvular means (20). The connection device (46) comprises a plurality of hold members (47) suitable to engage flange means (13, 23) of reciprocal union of the valvular means (10, 20) and carried respectively by first and second hold means (49, 50) arranged mobile on a plane substantially transverse to the axis of the valvular means (10, 20) and linked at one end to an elastic tightening member (58). At the opposite end of the first and second hold means (49, 50) acts a clamping member (63) pivoted on the first hold means (49) and suitable to couple up the second hold means (50) driven by an actuator member (69) through a leverage (72) articulated to the same first hold means (49).
