<p>Pipe stub (1) for connecting a hose (2) provided with a clamp collar (4) having, on its external portion which is applied against the inner surface of the hose (2''), several annular grooves (7) with an annular profile. The flanks of the profile (8 and 9) are on one side oriented towards the free end of the stub (1) and are designed with a relatively steep angle of approximately 45?o to 75o¿, and on the other side face away from the free end of the stub (1) and lie at a relatively small, gently-tapered angle of approximately 20?o to 40o¿, thus creating relatively large tapered support surfaces for the inner surface of the hose (2''). The depth of the annular grooves (7) is relatively small, 1:20 to 1:50 in comparison with the outer diameter of the stub (1). The peaks and valleys of the grooves are considerably rounded off preferably with the same curvature radius (R1) as the depth of the annular grooves (7), namely 1 mm.</p> |
