A security sector (27) of the bolt (7) has a bevelled part (29) which moves the locking pin (10) back into its release position when the security sector (17) moves relative the bolt locking sector (15). This is supplemented by a recessed part (33) on the bolting sector (15) end furthest from the security sector (17), all reinforced by the locking flange (32) ringing the recessed part (33), and a bevelled part (34) at the axially opposing end to the recess. The bevelled part (34) in turn re-activates the pin (10) so this homes under spring load (12) into the security sector (17) groove way (27). |
