1. A pin locking device for locking a first sealing component of a seal cartridge together with a second sealing component of said seal cartridge, the pin locking device comprising:
a pin body comprising a longitudinal bore extending along a longitudinal axis, wherein an inner wall of said bore comprises fixing means configured for cooperating with an extraction tool, the pin body comprising two parts arranged longitudinally one after the other along said longitudinal axis, namely a first part configured for fitting a pin cavity of the first sealing component and a second part configured for fitting a locking cavity of the second sealing component; and
a spring configured for exerting a spring force against the pin body along said longitudinal axis, wherein said spring is configured for leaning, on one side, on a first contact surface of the pin cavity and for having its other side contacting a second contact surface, wherein said second contact surface is a surface of the pin body on which said bore opens out, wherein the spring force is configured for moving the pin body from a withdrawn position, where the pin body is entirely located within the pin cavity, towards a locked position where said second part is located and maintained within the locking cavity while the first part remains located within said pin cavity.
