A device for applying a lock solution in a catheter or other access system comprises a syringe (302) having an expulsion arrangement (305, 311) for expelling the lock solution from the device, said expulsion arrangement including a plunger (305) arranged in a housing (304), further comprising a sterile connector (303) for connecting the syringe (302) to the catheter. The connector (303) is arranged to engage a tip (307) of the expulsion arrangement (305, 311) tightly when the syringe (302) is inserted in the connector (303). The connector (303) is arranged to prevent the tip (307) of the expulsion arrangement (305, 311) from entering the catheter. The tip (307) is frangible. A method of applying a lock solution in a catheter or other access system is also disclosed.
