The invention relates to a sliding sleeve (1) for axially sliding onto an expanded end of a solid plastic tube (4) or a plastic composite tube, wherein a connection element (3) support body (5) which is provided with circumferential outer ribs (7, 7a, 7b, 7c) is inserted into said end. The sliding sleeve (1) is made of an elastically deformable polymer material. The inner surface (2) of the sliding sleeve (1) has an average roughness Ra ranging from 1 µm to half of the average wall thickness of the sliding sleeve (1), or the inner surface (2) of the sliding sleeve (1) has a plurality of macroscopic uneven sections, the depth of which does not exceed half of the average wall thickness of the sliding sleeve (1). La invención es concerniente con un manguito deslizante (1) para deslizarse axialmente sobre un extremo expandido de un tubo de plástico sólido (4) o un tubo compuesto de plástico, en donde se provee un cuerpo de soporte (5) del elemento de conexión (3) que es provisto con nervaduras circunferenciales externas (7, 7a, 7b, 7c) se inserta al extremo. El manguito deslizante (1) es fabricado de un material polimérico elásticamente deformable. La superficie interna (2) del manguito deslizante (1) tiene una rugosidad promedio Ra que varía de 1 µm a la mitad del espesor de pared promedio del manguito deslizante (1) o la superficie interna (2) del manguito deslizante (1) tiene una pluralidad de secciones desiguales macroscópicas, la profundidad de las cuales no excede la mitad del espesor de pared promedio del manguito deslizante (1).
