Abstract
A hose connecting assembly comprises a connecting tube 1 made of a resin, flexible hoses 21, 22 and 23 each having a reinforced layer which is braided with reinforcing threads, into which the connecting tube 1 is inserted, and a resin cover 3 which covers coupling portions between the hoses and the connecting tube integrally therewith. The cover 3 is formed by molding and includes a reinforcing filler and has a post-shrinkage factor of 0.2 to 0.9%. The hoses have inner diameters which have been increased 10 to 30% by the insertion of the connecting tube 1 thereto. Stress cracks are prevented from occurring and high sealing pressure is provided.
