Claim:
1. A releasable blocking system of a catheter, comprising a base adapted to receive a catheter, and a shell, rotatably mounted on the base between an open position, in which the shell is away from the base, and a closed position, in which the shell is hooked on the base and blocks the catheter in position, wherein: the base defines a housing having a principal direction according to a longitudinal axis, said housing enclosing a sleeve provided with a blocking aperture extending along the longitudinal axis and adapted to abut against a distal wall of the housing, wherein the housing comprises successively, along the longitudinal axis, a blocking chamber and a ring, a channel extending between the blocking chamber and the ring, the system comprises an actuator provided with a guide aperture extending along the longitudinal axis and mobile in translation along the longitudinal axis in the housing between a rest position and a blocking position in which the actuator applies an axial force to the sleeve to deform it, the actuator comprising a first drive element, the blocking aperture and the guide aperture are adapted to receive a catheter, the shell comprises a second drive element, adapted to cooperate with the first drive element of the actuator when the shell is shifted from its open position to its closed position, and shift the actuator along the longitudinal direction to its blocking position, and wherein the first drive element of the actuator has a return ramp extending outwardly from a distal part of the actuator and protruding between the blocking chamber and the ring of the housing through the channel, and the second drive element comprises a projecting part extending from the shell, arranged so as to penetrate the channel of the housing and come into contact with said return ramp when the shell is brought to its closed position.
