The device ( 10 ) comprises a stationary body ( 12 ), a pincer member ( 14 ) comprising first and second pincer branches ( 14 A, 14 B) mounted to move in the stationary body ( 12 ) between a rest position and a cocked position, return means ( 16 ) for resiliently returning the pincer member ( 14 ) to the rest position, and locking means ( 18 ) for locking the pincer member ( 14 ) in the cocked position against the return force of the pincer member ( 14 ), and releasable by means of a trigger member ( 20 ) that can be activated by a user. The device ( 10 ) further comprises blocking means ( 32 ) for blocking the pincer branches ( 14 A, 14 B) in a pinched-together position, which blocking means are active during a displacement stroke of the pincer member ( 14 ) between its cocked position and its rest position, without the user needing to maintain any action on the trigger member ( 20 ).
