DEVICE FOR SCREWING TOGETHER MEDIUM-GUIDING THREADED CONNECTIONS, PARTICULARLY LUER LOCK CONNECTIONS

摘要

Disclosed is a device comprising an outer part (5) and an inner part (9) that is accommodated therein. Longitudinal grooves (11) are provided within the inner part (9) so as to receive longitudinal ribs of an injection needle. Protrusions (13) that are disposed on the outer part (5) and recesses (14) which are arranged within the inner part (9) allow the inner part (9) to be twisted only in one direction relative to the outer part (5) while putting up resistance to said twisting movement. A spring (12) tenses the outer part (5) and the inner part (9) counter to each other in an axial direction.
