Frictional damper

A frictional damper comprising:

• a tubular housing having a longitudinal axis;
• a tappet, which is displaceable in the housing along the longitudinal axis and is led out at an open end of the housing;
• a frictional element lying against the tappet;
• a cap attached to the open end of the housing with axial prestressing relative to the longitudinal axis;
• and
• at least one latch hook arranged on the housing, wherein the at least one latch hook engages in a latch recess of the cap, wherein the latch hook has a latch hook length which is oriented along the longitudinal axis and which in the disassembled state of the cap is greater than an axial latch recess interval of the cap, the latch hook length being defined by an axial distance of an end face of the housing from a lug end face of the lug, the lug end face being arranged remote from the end face, wherein the axial latch recess interval defines an axial distance of a groove flank of the external groove from an underside of a radial flange of the cap, the groove flank being remote from the underside.
