The pedestrian protection device includes a second body element that includes a hollow profile section. The first body element is movably received in the hollow profile section. The pedestrian protection device includes an elastically deformable exterior component connected to the second body element. The hollow profile section of the second body element is displaced from a rest position to a crash position upon the application of force against exterior component. The pedestrian device includes a latching device that releasably latches the connecting section of the first body element with the hollow profile section of the second body element when set in the crash position. ## Claims ### Claim 1 A pedestrian protection device of a vehicle, comprising: a vehicle-mounted first body element comprising a connecting section;
