A device for protection against entrapment for a door for a vehicle includes an extruded profile extruded from an elastomer material, wherein the extruded profile includes a door leaf wall, which faces a contact edge of a door leaf of a door when the device is mounted on the door, a sealing wall arranged in an opposing position relative to the door leaf wall and a plunger for transferring a compression force into the extruded profile. The plunger is mounted on the sealing wall and extends along a transverse axis of the extruded profile away from the door leaf wall. The device also includes at least one switching element for detecting a compression of the extruded profile, wherein the at least one switching element is arranged in the region of the plunger between the door leaf wall and the plunger.
