1. A fixing device for fixing a catheter assembly to a patient, the fixing device comprising:
a receiving unit having a bottom surface provided for connection to a skin surface of the patient,
a receiving recess, which is arranged on the receiving unit to receive and frictionally engage a portion of the catheter assembly, and
a closure unit comprising a first side portion non-releasably joined to the receiving unit on a first side of the receiving recess, and a second side portion provided separately from the first side portion and non-releasably joined to the receiving unit on a second side of the receiving recess such that the closure unit does not extend between the receiving recess and the bottom surface of the receiving unit, wherein the first side portion and the second side portion are movable relative to the receiving recess between an opened state of the closure unit, in which the receiving recess is open for receipt and/or removal of the portion of the catheter assembly, and a closed state of the closure unit, in which the receiving recess is at least partially closed by the closure unit,
the receiving unit comprising a flexure portion between the receiving recess and the bottom surface of the receiving unit, the flexure portion defining a region about which a first portion of the bottom surface flexes relative to a second portion of the bottom surface when the closure unit is moved between the opened state of the closure unit and the closed state of the closure unit,
the receiving unit being designed with shape elasticity throughout the flexure portion, such that the closure unit is movable between the opened state of the closure unit and the closed state of the closure unit by an elastic deformation of the receiving unit at the flexure portion,
the receiving unit being made of a flexible plastic,
the closure unit being made of a substantially dimensionally stable plastic;
wherein:
the receiving unit is monolithically formed from a first plastic material which is the flexible plastic,
the closure unit is made of a second plastic material which is the substantially dimensionally stable plastic and wherein the second plastic material is different from the first plastic material, and
the first plastic material extends continuously from the receiving recess to the bottom surface of the receiving unit.
