Abstract
A fire protection sleeve segment can be arranged for a fire protection sleeve for sealing a combustible body penetrating an opening in a wall or ceiling in the event of fire. The fire protection sleeve segment contains a first housing element and a second housing element, wherein the housing elements have a boundary wall containing a contact surface and an outer surface opposite the contact surface. The two housing elements are rigidly interconnected and arranged so as to be stepped with respect to one another. An intumescent material is applied to the contact surfaces. To form a fire protection sleeve, a plurality of fire protection sleeve segments are arranged relative to one another and interconnected such that the intumescent material applied on the contact surface of the first housing element is covered, in whole or in part, by the second housing element of the respectively adjacent fire protection sleeve segment.
