1. An electric heater, comprising:
an axial opening for receiving an object to be heated;
an electric heating element at least partially surrounding said axial opening;
a cylindrical or frustoconical clamping jacket surrounding said electric heating element at least in a radial direction for generating an adjustable force acting radially in a direction of an axis of said axial opening, said clamping jacket comprising a multipart clamping jacket and at least one pressing segment for introducing said force acting radially in said direction of said axis of said axial opening, said clamping jacket further comprising at least one clamping segment, wherein a width of a gap between adjacent edges of one or more pressing segments is varied for adjusting said force acting radially in said direction of said axis of said axial opening by moving said clamping segment relative to said at least one pressing segment, wherein said recesses and/or guide elements and/or contact surfaces between said clamping segment and said pressing segment have a surface with surface roughness or a ribbing.
