A gas turbine engine cowl has a portion which translates axially of the remainder, to open or close a reverser gas flow gap. A yoke is attached to the fixed cowl upstream of the gap which yoke is engageable with a member on the translating cowl portion, by dropping thereover as the cowl portion closes the gap. Translation of the cowl portion actuates an abutment via a cam mechanism to release the yoke at such a time as to prevent the yoke dropping too soon, which would result in the cowl portion being unlocked.
