Abstract: A crimp sleeve connector is provided for the secure connection of a tube and a fitting. The crimp sleeve connector is substantially positionable on the fitting and the tube is inserted between the fitting and the crimp sleeve connector. The connector includes a crimp ear which extends through the body of the crimp sleeve connector. At least one o-ring is fitted over the fitting in such a position that when the tube, fitting and crimp sleeve connector are in place the o-ring functions to maintain a fluid-tight seal. An alternative embodiment of the crimp sleeve connector includes a crimp indicator in the form of a band which falls away after crimping, thus allowing visual confirmation that the crimp ear has been crimped.
