A device suitable for use in inserting a pin into an object comprises an elongated pin driver and an elongated pin which are engaged by a locking mechanism. The locking mechanism moves the device to a first locking position when the pin is inserted into the pin driver such that each of first and third abutment surfaces associated with a first abutting member of the pin driver and with a stud portion of the pin, respectively, abuts against one another, and such that each of second and fourth abutment surfaces associated with the first abutting member of the pin driver and with a second abutting member of the pin, respectively, abuts against one another in order to prevent the pin driver and the pin from rotating relative to each other in a first direction. The locking mechanism further moves the device to a second locking position when the pin driver and the pin are rotated relative to each other in a second direction substantially opposite the first direction until each of second and fifth abutment surfaces associated with the first abutting member of the pin driver and with a slot in the pin, respectively, abuts against one another which in turn causes the first abutting member to be captured inside the slot. Moving back the device to the first locking position by rotating the pin driver and the pin relative to each other in the first direction allows the pin to be readily pulled out of the pin driver.Linvention concerne un dispositif destiné à être utilisé lors de lintroduction dune broche dans un objet, comprenant un mandrin de broche allongé et une broche allongée qui sont solidarisés par un mécanisme de blocage. Le mécanisme de blocage déplace le dispositif dans une première position de blocage lorsque la broche est introduite dans le mandrin de broche de manière telle quune première surface de butée et dune troisième surface de butée, associées respectivement à un premier élément de butée du mandrin de broche et à une partie de tige de la broche, butent lune c
