A blocking unit (100) for telescopic sections (300) comprising a first engaging part (110) movable between a disengaged position (dis) and an engaged position (imp), a first hydraulic cylinder (1a, 1b) which moves the first engaging part, a first movement part (130) of blocking pins (400) movable between a first position (p) and a second position (s), a second hydraulic cylinder (2) which moves the first movement part, a first (5) and a second (6) safety hydraulic cylinder (5) comprising a chamber (52, 62) and a movable part (51, 61) which passes from a rest position (rip) to an extended position (est) and a hydraulic circuit. The movable parts (51, 61) are respectively movable in the direction of the first engaging part (110) and of the first movement part (130) and in the extended position (est) the hydraulic fluid in the chambers (52, 62) oppose the return into the first (p) or disengagement position (dis).
