ABSTRACT:
Nuts used in a conventional tube union connector are prevented from rotating, which would compromise the connector, by mounting a pair of resilient clips over the nuts, the clips having elongated serrated latch members which interlock together to prevent such loosening. This lightweight device is quickly installed and requires no special installation tooling.
