Fastening device for connecting at least one hose to a threaded stem

摘要

A fastening device (1) for connecting at least one hose to a threaded stem (3) has a supporting body (10) provided with an attachment portion (11) and a side clamp (12) configured in such a way as to be tightened around the hose; the attachment portion (11) has an external portion (20) and a softer internal portion (21) which defines a through hole (22); the fastening device also has a fastening pin (31) with an axial stem (34), which is axially hollow for housing the threaded stem (3); the axial stem (34) is inserted in the through hole (22) and remains in contact with the softer material of the internal portion (21), which therefore cooperates in damping vibrations.
