A manual connector (1; 101), adapted to connect two conduits intended to conduct a fluid, the manual connector (1; 101) comprising: - a first connector element (2; 102), including at least two retaining portions (5, 6); - a second connector element (3; 103), adapted to receive the first connector element (2; 102) in a longitudinal direction, the second connector element (3; 103) including at least two clamping members (8, 9; 108, 109) disposed in the second connector element (3; 103), each clamping member (8, 9) being displaceable at least in rotation and between a clamping position, in which each clamping member (8,9) cooperates with a respective retaining portion (5, 6) so as to fasten the first connector element (2; 102) in the second connector element (3; 103), and a position called unclamping position, in which each clamping member (8, 9) releases a respective retaining portion (5, 6); and - handling means configured to displace each clamping member (8, 9) between the clamping position and the unclamping position; the handling means are configured so that the rotation of a respective clamping member (8, 9) is done about a direction of rotation which is orthogonal to the longitudinal direction; and the handling means comprise a gripping member (11; 111) adapted for a gripping by an operator, for example a handle, the gripping member (11; 111) being linked to each clamping member (8, 9) so that an actuation of the gripping member (11; 111) by the operator, for example in pivoting, drives in rotation the two clamping members (8, 9), the first connector element (2; 102) having on its outer surface at least two insertion portions (21, 22) defining a transverse dimension (21.22), measured orthogonally to the longitudinal direction, which is smaller than the distance (8.9) separating the two clamping members (8, 9), so that the second connector element (3; 103) can be pivotally displaced about the longitudinal direction between: - an insertion position, in which the insertion portions (21, 22) can slide between the clamping members (8, 9) so as to insert the first connector element (2; 102) into the second connector element (3; 103) in translation in the longitudinal direction; and - a retaining position, in which the retaining portions (5, 6) abut respectively against the clamping members (8, 9) so as to retain the first connector element (2; 102) in the second connector element (3; 103) - characterized in that it further comprises a locking device arranged to be adapted to block the rotation of at least one clamping member (8, 9), this locking device comprising a pin and an elastic biasing member, the pin being manually displaceable between a locking position, in which the pin partially penetrates into a cavity formed in an axis secured in rotation with one of the clamping members, and an unlocking position, in which the pin is disengaged from the cavity, the elastic biasing member being arranged to bias the pin in the locking position. - a first connector element (2; 102), including at least two retaining portions (5, 6); - a second connector element (3; 103), adapted to receive the first connector element (2; 102) in a longitudinal direction, the second connector element (3;
