An adhesive dispenser comprises a barrel (2) which houses a deformable pipette charged with adhesive and having a nozzle (3) projecting from one end of the barrel. Dispensing buttons (7) carried by the barrel (2) are squeezed to compress the pipette to dispense adhesive through an outlet passage (26) of the pipette nozzle. A protective cap (4) screws onto a mounting boss at the one end of the barrel to enclose the projecting pipette nozzle (3). Pin means (54) is carried by the caps (4) and comprises a pin (59) for penetrating the outlet passage (26) of the pipette nozzle (3) and a pin shroud (60) surrounding the pin (59) and fitting over the pipette nozzle (3) when the cap (4) is attached to the barrel (2). A locking sleeve (5) is mounted on the one end of the barrel (2) and is movable into an operative position in which the sleeve prevents rotation of the cap (4). |
