Is that a spade connector?  If so, and if the female connector is
accessible, you can squeeze the ears with needle-nose pliers.  After
that, it may be a bit harder to insert the male spade the first time,
but that's a good thing, because it means a good electrical contact
will result.

I like to replace spade and ring connectors with the better quality
AMP versions we use in the aircraft.  Here's one source:

These connectors have two metal barrels: One is crimped on the wires
and the other on the insulation for strain relief.  Here's the proper
crimp tool:
