A securing device for an introducer of the kind for introducing an oral tube or laryngeal mask into a patient takes the form of a V-shape plate with a ribbed collar at its apex within which the tube or mask extends. A compressible gap extends from the collar to the edge of the plate and this is compressed, so that the collar grips the tube or mask, by fastening openings in the plate onto projections from the introducer. Alternatively, the securing device has a clip with two spaced engagement members so that the gap is squeezed closed by clipping the engagement members between two arms of the introducer.
