A reinforcing slat for use in an inflatable packer which is elongate and curved about its longitudinal axis and comprises perforations in the part thereof which enters the end portion and which bends around the end portion on inflation of the packer. The perforations serve to reduce the bending stiffness of the slat in the portion likely to suffer permantent deformation on inflation of the packer.
