Claim:
A door sealing element for sealing a gap between a lower edge of a movable door and a stationary floor mating face, comprising a first and a second piece of flexible tubing, the first and the second pieces of flexible tubing are connected to each other at a connection, such that they communicate at respective first ends thereof, the first piece of tubing further having a second open end, the first piece of tubing to be provided in the region of the lower edge and the second piece of tubing to be provided in the region of a lateral door edge to be moved against a stationary stop surface in a closed position of the door, whereby the first and the second pieces of tubing are configured, such that by means of elastic compression of the second piece of tubing, a defined air volume is displaced from the second piece of tubing into the first piece of tubing, and thus the first piece of tubing is elastically expandable to seal the gap, a closing device is provided which closes the second piece of tubing at a point on its longitudinal extension by mechanical clamping in the direction of the second open end of the second piece of tubing, which lies opposite to the connection with the first piece of tubing.
