1. A sealing strip for bendably mounting on a flange about an axis, comprising a channel-shaped flexible material and a reinforcing carrier embedded within the flexible material, the carrier comprisingreinforcing material extending continuously along the sealing strip but provided with a plurality of slots, the reinforcing material being in the form of a channel of generally U-shaped cross section having a base integrally connected to a first and second side wall,each slot running transversely to the direction of extension of the channel and extending from a distal edge of a side wall into the base of the reinforcing material but stopping short of the distal edge of the other side wall,the slots being of a first type and of a second type, each slot of the first type extending from the distal edge of the first side wall across the base of the channel to the second side wall and each slot of the second type extending from the distal edge of the second side wall only part way across the base so that the reinforcing carrier is less elastically compressible in a longitudinal direction along said second side wall than along said first side wall to minimize puckering of the flexible material adjacent the second side wall when the sealing strip is bent about the axis with the second side wall closest to the axis.
