An air spring has a pair of axially spaced end members and an intervening elastomeric flexible sleeve extending therebetween which forms a fluid pressure chamber. A plurality of axially spaced ribs and intervening grooves are formed on an inner surface of a ring which align with corresponding ribs and grooves formed on an axial sealing surface of one of the end members to form a fluid tight seal with the elastomeric sleeve clamped therebetween. An annular radially extending projection is formed on each of the ring and end member which cooperatively mate with each other to provide a mechanical interlock therebetween which is free of intervening elastomeric material, to securely retain the ring in position with respect to the end member sealing surface.
