The support includes a tubular casing (1), whereby the remaining components of the support are accommodated in the interior of this casing. A stop (15,16) exists at the respective end of the casing. An end piece (12,13) is accommodated in the respective end portion of the casing (1) whereby the outer front surface (22,34) of the respective end piece rests on the assigned stop (15,16). A terminating or closing device (25,26) is assigned to that one side of the respective end piece, which faces the interior of the support, whereby a tubular interior part (10) extends between said terminating devices. A sealing ring (35) is arranged between the front surface (22,34) of the respective end piece (12,13) and the assigned stop (15,16). The outer diameter of this sealing ring (35) before the assemblage of the support is equal to the outer diameter of the remaining components lying in the interior of the support or it is smaller than the diameter of the remaining interior parts.
