ABSTRACT:
Two components, such as a support tube (4) and handset (2) of a herbicide delivery lance, are interconnected in a manner which provides an electrical connection between leads (56, 38) in the tube (4) and the handset (2) respectively. Fluid communication is also provided between a flexible tube (44) in the tube (4) and a passage (26) of the handset (2). The leads (56) on the tube (4) are connected to two terminal plates (58) situated on the outer surface of the tube (4). These terminal plates (58) move into position opposite bosses (32) on a sleeve (28) provided on the handset when the tube (4) is pushed into the sleeve (28). Screws (40), engaging bushes (36) accommodated in the bosses (32), are then screwed into contact with the terminal plates (58) to secure the tube (4) in position. The screws (40) also complete the electrical circuit between the leads ( 56, 38). One of the components includes a valve (16, FIG. 5) which includes an operating member (110). Displacement of the operating member against the action of a spring (122) not only opens the valve, but also actuates an electrical switch (140).
