The invention relates to a float (,) for buoyant hoses comprising at least one multi-layer foam body which surrounds the buoyant hose (,), whereby the foam body is composed of individual foam sheets (,). Inside a layer, a radial connection (,) is produced which adheringly joins two adjacent foam sheets (,) to one another. In addition, the float comprises an axial connection (,) which also adheringly joins two adjacent foam sheets (,) to one another from sheet to sheet. According to variant A, the radial connection (,) is exclusively produced by a layer made of a polymer material which expands when heated and occupies a large volume. According to variant B, both the radial connection (,) as well as the axial connection (,) are produced by a layer made of a non-expandable polymer material, whereby the individual layers are joined to one another for the radial and axial connection in such a way that each foam sheet (,) is completely single chambered.
