The elongate clip (2) has one slot (7, 8) respectively in each of its two end portions, the first slot (7) having a width equal to the diameter of the neck portion (5) of the screw pin (1) and being oriented in longitudinal direction of the clip (2), the second slot (8) narrowing to a width smaller than the diameter of the neck portion (5) of the screw pin (1) and then enlarging to a diameter equal to the diameter of the neck portion (5) and the second slot (8) being oriented normal to the longitudinal direction of the clip (2). This system has the advantages of convenient installation and stable fixation. ## Claims ### Claim 1 System for mounting a refrigerant compressor housing (11) to a base plate (9) having threaded holes (10), the system comprising at least two screw pins (1) and one clip (2) to connect the two screw pins, characterised in that each screw pin (1), as seen in its longitudinal direction, has a threaded portion (3) for screwing the screw pin (1) into a threaded hole (10) of a base plate (9), the threaded portion (3) being followed by a middle portion (4) to be inserted into a respective opening (17) of a refrigerant compressor housing (11), the middle portion (4) being followed by a neck portion (5) having a smaller diameter than the middle portion (4), the neck portion (5) being followed by a head portion (6), the head portion (6) having a larger diameter than the neck portion (5), the system being further characterized in that the elongate clip (2) has one slot (7,8) in each of its two end portions, the first slot (7) having a width equal to the diameter of the neck portion (5) of the screw pin (1) and being oriented in longitudinal direction of the clip (2), the second slot (8) narrowing to a width smaller than the diameter of the neck portion (5) of the screw pin (1) and then enlarging to a diameter equal to the diameter of the neck portion (5) and the second slot (8) being oriented normal to the longitudinal direction of the clip (2). ### Claim 2 (depends on 1) System according to claim 1, characterised in that the enlarging portion of the second slot (8) is again followed by a second narrowing portion which portions correspond to the outer dimensions of the neck portion (5) of the screw pin (1) in order to hold the neck portion (5) within the enlarging portion and the second narrowing portion of the second slot (8). ### Claim 3 (depends on 1) System according to claim 1, characterised in that the clip (2) is made of sheet metal. ### Claim 4 (depends on 3) System according to claim 3, characterised in that around the second slot (8) the clip (2) has at least one flap (18,14) which is formed from the sheet metal of the clip (2) by folding the sheet metal normal to the plane of the clip (2). ### Claim 5 (depends on 4) System according to claim 4, characterised in that a first flap (13) is oriented parallel to the second slot (8). ### Claim 6 (depends on 5) System according to claim 5, characterised in that a second flap (14) is oriented normal to the second slot (8) and facing away from the entrance of the second slot (8). ### Claim 7 (depends on 1) System according to claim 1, characterised in that it comprises four screw pins (1) and two clips (2) and that the first clip is the mirror image of the second clip. ### Claim 8 (depends on 1) System according to claim 1, characterised in that the head portion (6) of the screw pin (1) has indentations or lobes (12) in order to allow the screw pin (1) to be screwed in by hand or with a tool. ### Claim 9 (depends on 1) System according to claim 1, characterised in that the system further comprises a refrigerant compressor housing (11) and a base plate (9) having four threaded holes (10), four screw pins (1) being screwed into the base plate (9), the middle portion (4) of each screw pin (1) being in a respective opening (17) of a leg (15) of the refrigerant compressor housing (11), the leg (15) or the refrigerant compressor housing (11) contacting the base plate (9), the first clip (2) having its first slot around the neck portion (5) of a first screw pin and the second slot (7) around the neck portion (5) of a second screw pin (1), the second clip having its first slot (7) around the neck portion (5) of a third screw pin (1) and the second slot (8) around the neck portion (5) of a fourth screw pin (1).
