A fluid check device (1) comprises a main body (2) exhibiting a fluid passage channel (3), an obturator (6) internally of the main body, a transmission rod (8) connected with the obturator, and a manoeuvring organ (12) engaged to the transmission rod for manoeuvring the obturator between a first and a second operating position. A removable stop element (15) axially constrains the manoeuvring organ (12) to the transmission rod and an auxiliary body (16) exhibits an anchoring portion (17) located in a radially external position with respect to the stop element and at least a gripping portion (18) activatable such as to disengage the auxiliary body and the stop element conjoinedly from the transmission rod. A tool (40) is used for engaging and disengaging the assembly constituted by the stop element (15) and the auxiliary body (16) with respect to the rod (8). |
