Abstract

There is disclosed a connector for attachment of flexible plastic tubing which is most compatible with filament reinforced tubing which resists elastic expansion. The connector has a central radial flange with opposite cylindrical ends which provide mandrels to receive adjacent ends of tubing. A cylindrical cage surrounds the cylindrical ends and supports chuck members. A pair of collet members are provided which slide over the tubing and the chuck members, compressing the chuck members radially inwardly without axial movement of the chuck members relative to the tubing. This deflects the chuck members into the wall of the tubing, thereby locking the tubing securely onto the mandrel. The collet member has an internal annular groove on its inside wall which receives an outer edge of the chuck members, thereby serving as a detent or interlock to resist the retraction of the collet member once it is moved into final position.
