The subject of this invention is a sleeve for fitting soft pipes quickly; thanks to its specific form this sleeve ensures a more even grip on the pipe and at the same time prevents possible damage to it, which otherwise may occur because of squeezing; it is appropriate for pipes with a small diameter. This sleeve for the fast fitting of soft pipes enables the solution of this technical problem by the seamless or jointless rim which fits around the pipe; the place of squeezing is protected by extending the circle arc, which prevents the pipe entering the squeezing area. By squeezing the sleeve's upper part (4) the diameter of the rim will be reduced and grip the pipe tightly.
