摘要

1. Coupling of the quick-acting type for pressurized-fluid systems whereby the pressure can reach one hundred and fifty bar, comprised of a body (2) having a bore (3) in which is located a reinforcing sleeve (21) intended for the centering of the pipe or hose (9) to be coupled, in the bore (3) being engaged, moreover, a retaining washer (4), an expansion ring (5), a seal (6) and an upper retaining ring (7), characterized in that said body (2) has, in its bore (3), a first set-back (13) limited by a shoulder (15) and in which is set the upper retaining ring (7), same comprising a set-back (62) the shoulder (63) of which acts as a stop for a crimping (64) of the body (2), said upper retaining ring (7) maintaining into position the seal (6), the expansion ring (5), the retaining washer (4), the reinforcing sleeve (21) as well as the hose or pipe to be coupled (9), in the second set-back (16) of the bore (3) of said body (2) when the fluid is pressurized.
