Abstract
In connection with an arrangement for fastening a corrugated pipe (11) on an essentially hollow-cylindrical connector (12), at least one spring leg (15), which extends at a radial distance from and in a longitudinal direction to the connector (11) and has a retaining lug (18) radially projecting toward the latter, is formed on the connector (12), and an annularly-shaped clamping element (20) is placed on the outside around the corrugated pipe (11) pushed onto the connector (12), which generates a radial clamping force directed toward the corrugated pipe (11) on the at least one spring leg (15), for providing a dependable and simple connection technique (FIG. 2).
Claims11
An arrangement for fastening a corrugated pipe to an essentially hollow-cylindrical connector in fuel-delivery units of motor vehicles, the arrangement comprising a fuel tank having a flange at least one leg which extends in a radial direction and in a longitudinal direction in relation to said connector and has a retaining lug projecting radially toward said connector;
- an annularly-shaped clamping element placed on an outside around said at least one spring leg and around said corrugated pipe pushed onto said connector so as to generate a radial clamping force directed toward said corrugated pipe on said at least one spring leg, said connector and said spring legs with said retaining lugs being formed of one piece on said flang of said fuel tank, said connector constituting a pipe section protruding from said tank flange toward a tank interior for a fuel delivery line, said corrugated pipe forming a fuel delivery line of a fuel delivery unit of a motor vehicle and a component of the fastening arrangement.
