There is a little knob on top of RJ connectors, for example, the RJ45 Ethernet connector. I guess the function of this knob is to keep the connector plugged in even if the wire is accidentally tugged away.
Is there a name for the knob in particular, or for such a connector type in general?
Usage example:
It is better to use _________ connectors, as they ensure that network is less likely to become accidentally disconnected.
