ABSTRACT:
A sealing arrangement has two bodies with two end faces which extend along a longitudinal axis, adjoin one another while forming a gap, the width of which can vary between zero and a maximum width. The gap is covered by a sealing strip which lies transversely to the gap, extends along the longitudinal axis and is mounted with clearance in two opposite grooves of a predetermined depth. In such a sealing arrangement, an increased maximum width of the gap is made possible by the sealing strip having a basic width transversely to the longitudinal axis, this basic width being less than or equal to twice the depth of the grooves, and by the sealing strip is constructed to prevent the sealing strip from slipping out of the grooves if the sum of the maximum width of the gap and the depth of the grooves is greater than or equal to the basic width of the sealing strip.
