Provided is a retention and safety device for hoses including a connection end engageable to a fixed point of a system. The device may include: (1) a rope defining a main extension trajectory and including an engagement portion; (2) a coupling end secured to the rope and connectable to the fixed point; and (3) an engagement end connectable to the hose and including the engagement portion of the rope and a rope guide bushing slidingly constrained to the rope and enclosing at least two portions distant along the main extension trajectory and mutually juxtaposed to the rope. The engagement portion may be substantially continuous and define a complete turn making, by means of a fast knot, an engagement loop in use around the hose, so that the engagement portion can wind around the hose irreversibly clenching along the same if the device is placed in traction.
