Spark plug boot not connecting

[WiMiMc]

so i found out one of them is loose, however when i try to reconnect it simply wont accept it and i dont hear the click. the spark plug is tight. is it something wrong with the boot?

Could be the connector is broken or pulled out... OEM wires or aftermarket?

They are known to come apart if you pull from the wire itself or are a little too rough with it.
