The dispenser has a body (1), with a mouthpiece cover (2). Opening of the cover urges a junction member (3) towards a source (4) of a medicament to be released as a dose by pressing a spout (5) of the source inwards of the source. The source is supported by a cap (11) clipped to the end of a source-enclosing barrel (12) with intern al splines (10). The barrel is welded (15) to the main to part (16) of the body at a position determined by the extension of the source towards the distal end (17) of the barrel when the cover is open, the welding position being determined by a plug (18) simulating the cap and its bush.
