Parking brake for a vehicle, in which the parking brake comprises: - at least one hydraulic system, in which the at least one hydraulic system comprises at least one cylinder, in which the at least one cylinder can be actuated between at least one first position and one second position, and in which the at least one cylinder comprises at least one rod and at least one casing, - at least one actuator, in which the at least one actuator is coupled to the at least one cylinder such that the at least one actuator is able to change the at least one position of the at least one cylinder, in which the at least one actuator can be actuated between at least one braking position and one resting position, in which the braking position provides a first position of the cylinder, - wherein the parking brake comprises at least one retaining means, in which the at least one retaining means can be coupled between the at least one rod and the at least one casing, in which a first position of the at least one cylinder comprises the retaining means coupled to the at least one rod and/or to the at least one casing, - wherein the at least one retaining means comprises at least one second joining means, in which the at least one second joining means can be coupled to the at least one rod such that the first position of the at least one cylinder involves the at least one second joining means being coupled to the at least one rod and the second position of the at least one cylinder involves the at least one second joining means being separated from the at least one rod, characterized in that: - the at least one retaining means can be deformed in a direction substantially perpendicular to a coupling direction between the second joining means and the at least one rod, - wherein said at least one rod comprises at least one fitting means, in which the at least one fitting means is rigidly connected to the at least one rod, and in which the at least one second joining means can be coupled to the at least one fitting means, - wherein the second joining means comprises at least one hook, in which the at least one hook can be coupled to the at least one fitting means and wherein the at least one hook comprises at least one ramp arranged to facilitate sliding and release of the hook from the at least one fitting means when the driver releases the at least one actuator. - at least one hydraulic system, in which the at least one hydraulic system comprises at least one cylinder, in which the at least one cylinder can be actuated between at least one first position and one second position, and in which the at least one cylinder comprises at least one rod and at least one casing, - at least one actuator, in which the at least one actuator is coupled to the at least one cylinder such that the at least one actuator is able to change the at least one position of the at least one cylinder, in which the at least one actuator can be actuated between at least one braking position and one resting position, in which the braking position provides a first position of the cylinder, - wherein the parking brake comprises at least one retaining means, in which the at least one retaining means can be coupled between the at least one rod and the at least one casing, in which a first position of the at least one cylinder comprises the retaining means coupled to the at least one rod and/or to the at least one casing, - wherein the at least one retaining means comprises at least one second joining means, in which the at least one second joining means can be coupled to the at least one rod such that the first position of the at least one cylinder involves the at least one second joining means being coupled to the at least one rod and the second position of the at least one cylinder involves the at least one second joining means being separated from the at least one rod, - the at least one retaining means can be deformed in a direction substantially perpendicular to a coupling direction between the second joining means and the at least one rod, - wherein said at least one rod comprises at least one fitting means, in which the at least one fitting means is rigidly connected to the at least one rod, and in which the at least one second joining means can be coupled to the at least one fitting means, - wherein the second joining means comprises at least one hook, in which the at least one hook can be coupled to the at least one fitting means and wherein the at least one hook comprises at least one ramp arranged to facilitate sliding and release of the hook from the at least one fitting means when the driver releases the at least one actuator.
