Abstract

A convoluted boot made of thermoplastic elastomer for sealing an annular gap between two parts which are connected to one another so as to be rotationally fixed and articulatable relative to one another. The invention is especially useful in a constant velocity universal joint. The boot has two collar regions for being secured by a clamping element on the parts. A number of fold units extending between the collars. A base body is made of a thermoplastic material, and at least at one of the collar regions, is provided on its inside and outside with a coating. The coating material comprises a greater elasticity than the material of the base body.
