1. A photopolymerization device for treating plastic dental parts, having an irradiation space in an irradiation chamber (1), the space being accessible via at least one pivotable or displaceable wall, and having a light conductor (2) and a radiation source unit (3), wherein the light conductor (2) feeds the radiation from the radiation source into the irradiation space of the irradiation chamber (1) and forms a releasable connection between the irradiation chamber and the radiation source unit, wherein  said radiation source unit is a hand-held polymerization unit (3), having a housing part;  said irradiation chamber (1) is coupled to a support frame (4) including a first support (6) and a second support (7), disposed on a support plate (5) forming a part of said support frame (4); and  said hand-held polymerization unit (3) and said support frame (4) are formed with matching shapes adapted for rapid yet form-fitting engagement with one another to provide said releasable connection, said connection being formed upon engagement of said housing part in said first support (6) and of said light conductor (2) in said second support (7), said connection assuring fixation of the relative position of the polymerization unit and the chamber to thereby assure constant radiation conditions in said chamber.  characterized in that  the first support (6) is a platform-like part that has an opening (13) for receiving the hand-held polymerization unit (3).  characterized in that  the first support (6) has a slit (14) extending all the way from the opening (13) through to the outside.  characterized in that  the light conductor (2) has external sheathing that is connected to at least one of the irradiation chamber (1) and the hand-held polymerization unit (3).  characterized in that  the second support (7) holds the external sheathing of the light conductor (2), and the irradiation chamber (1) rests on the second support (7).  characterized in that  the irradiation chamber (1) is fastened to the support plate (5).  characterized in that  the irradiation chamber (1) has ribs (17) on its underside that partly enclose the outer contour of the support plate (5).  characterized in that  the hand-held polymerization unit (3) is retained in the first support (6) in a manner fixed against relative rotation.  characterized in that  the hand-held polymerization unit (3) has a protrusion (9) that engages the slit (14).  characterized in that  the hand-held polymerization unit (3) has an activation switch (12), the hand-held polymerization unit (3) being fixed in the support frame (4) in such a way that the activation switch (12) is located on a side remote from the support plate (5).  characterized in that  the support plate (5) forms the base plate of the support frame (4).  characterized in that  the axis of the light conductor (2) extends parallel to the support plate (5).  characterized in that  the light conductor (2) extends with its axis aligned horizontally. 2.
