Just make it snug with an open end wrench and bleed the line to remove air (make sure fluid reserve does not get low while bleeding).
hydraulic clutch does not have adjustment. replace the clutch it has a slave cylinder underneath and what you do is pump up the clutch and then hold it and have somone turn the line going itno th slave cylinder until you have clear fluid that is not how you bleed a clutch to the jeep owner, if you know how to bleed brakes on a vehicle, then you know how to bleed the clutch on a vehicle both done the same way.now if no parts of the clutch, such as master or slave cylander have been touched or let run out of fluid, there is still no need to bleed as that will not be the problem you might look at the linkage on the slave cylander. sometimes there is nylon bushing on the cylander rod that wears out. replace this bushing which is easy to do and your clutch will be good again.
Most likely the clutch master cylinder and/or slave cylinder has went out. It's a good rule of thumb to replace both at the same time to save frustration later on. A hydraulic clutch system works on the same principle as your brake system. Its very important that after replacing the slave and master cylinder that you properly bleed all air from the hydraulic lines to ensure proper clutch pressure.
Some cars have no valve and you have to loosten the line to bleed the cyl. Fill the slave cyl as full as you can get it before mounting it .
The slave cylinder is a plunger that releases the pressure on the clutch. When you step on the clutch pedal, fluid is forced into the slave which pushes out a rod that pushes against the fork that then pusher against the pressure plate that is between the motor and the transmission.
If it does this in all gears, I bet your clutch is shot. Other things that could cause problems are the Clutch master cylinder or clutch slave cylinder.
