A door arrester, in particular for a door of a motor vehicle, includes a door retainer rod (30) which can be mounted on either one of the door (2) or the body (3) so as to be pivotable and has a first side (35) with profiling (35a) formed on the first side (35); and a first braking element which can be arranged on the other of the door (2) or the body (3) and in sections bears against the first side (35) of the door retainer rod (30) under the effect of a preload, and which, with the profiling (35a) of the first side (35), defines at least one retaining position. The first braking element has a central boring, the door retainer rod (30) has an elongate through-hole (33), a guide pin (40) passes through the central boring and the through-hole (33), and the guide pin (40) permits an axial movement of the first braking element along the guide pin (40).
