ABSTRACT:
An elongated roller shutter profile of plastic or metal for swimming pool covers has a water-proof closure that closes an end of at learnt one longitudinal hollow chamber of the roller shutter profile. The closure includes a cap at least partly inserted from the end into the chamber, a piston plate spaced from the cap, and a sealing body between the cap and the piston plate. The sealing body made of an elastic and/or plastic material is brought into a sealing state by clamping between the piston plate and the cap so that the sealing body expands in width and rests in a circumferentially tight manner on the inner walls of the hollow chamber.
