ABSTRACT:
Retention element, especially a lid stay or a flap holder, comprising a first arm, having a first friction face, a second arm, connected pivotably around an articulation axis to the first arm, an operating element and a locking element, forming a locking face, wherein the locking unit is arranged to the second arm, a braking element, having a braking face, to which the locking face is held in frictional contact, and having a second friction face, which is held at least indirectly in abutment to the first friction face, wherein the operating element, in a first rotational direction of the arms relative to each other, urges the locking face against the braking face, wherein in the first rotational direction of the two arms relative to each other the maximal braking torque between the locking face and the braking face is larger than the maximal frictional torque between the first friction face and the second friction face, wherein in a second rotational direction of the two arms relative to each other the maximal braking torque between the locking face and the braking face is smaller than the maximal frictional torque between the first friction face and the second friction face and wherein the maximal frictional torque in the first rotational direction of the two arms relative to each other is larger than the maximal braking torque in the second rotational direction of the two arms relative to each other.
