ABSTRACT:
A coupling device is adapted for attachment to an elastomeric tubular body having integral, looped reinforcement fibers as part of a tubular assembly. The coupling device includes a coupling member, a stem and a mechanism for retaining the elastomeric tubular body in sealing engagement with the stem when connected therewith. The retaining mechanism maintains this engagement by being interposed within loops of the reinforcement fibers to limit axial movement of the reinforcement fibers relative to the stem. Thus, the grommet retained coupling and the elastomeric tubular body are maintained in spaced relation to and sealing engagement with each other.
