An inflatable lifejacket for providing buoyancy in water to a wearer of the lifejacket, comprises an inflatable buoyancy envelope and an inflation unit mounted within the envelope for inflation thereof. The inflation unit comprises a storage cylinder which stores inflation gas and which is openable by an operating arm which in an inoperative disposition extends alongside the cylinder in spaced relation thereto and which when pulled away from the cylinder in an operating stroke is operative to release gas from the cylinder. The envelope includes a projecting tongue portion which receives the arm and which is so positioned in relation to an adjacent support portion of the envelope that, when the unit is assembled in a mounted disposition in the envelope with the arm located in the tongue portion, the cylinder is aligned with the adjacent support portion and is supported thereby when the arm is pulled to release gas from the cylinder.
