Abstract
A permanent-wave or water-wave curler having an elongated cylindrical curler body with at least one holding body arranged at one end coaxially of the curler body axis. The holding body is greater in diameter than the curler body and has two axially spaced and radially extending flanges. The flanges have a resilient characteristic and substantially equal diameters to thereby define an annular groove therebetween. At least one of the flanges has a thickness slightly larger than the axial spacing between the two flanges so that when the one flange is inserted under force into a groove of an adjacent curler, the flanges on the adjacent curler will flex to permit entry of the one flange therebetween and effect a friction holding of the one flange against a rotation relative to the two flanges defining the groove.
