Claim 0:
1. An emergency opening device for an aircraft door comprising:
a tubular actuating member (2) having a first connecting end (3) and a second connecting end (4), the tubular actuating member (2) switches between a retracted rest position and a deployed open position;
an elastic compression device (11) designed to urge the tubular actuating member (2) from the retracted rest position toward the deployed open position;
a retaining member for retaining the tubular actuating member (2) in the retracted rest position with the elastic compression device (11) kept compressed;
a triggering device designed to release the retaining member and cause the tubular actuating member (2) to transition into the deployed open position under the effect of the expansion of the elastic compression device (11);
the retaining member has a retaining cord (12) which, when the tubular actuating member (2) is in the retracted rest position, is held taut between a first fastener (14, 17) at the first connecting end (3) and a second fastener (16, 18) at the second connecting end (4) of the tubular actuating member (2);
the triggering device has a transversely-severing member (22) for transversely severing the retaining cord (12).
