PCT No. PCT/AU87/00282 Sec. 371 Date Apr. 11, 1988 Sec. 102(e) Date Apr. 11, 1988 PCT Filed Aug. 21, 1987 PCT Pub. No. WO88/01447 PCT Pub. Date Feb. 25, 1988.A junction box (1) adapted to have releasably connected fittings (12,14,15,16,17) of variable inlet diameters and connections. The fitings (12,14,15,16,17) have castellations (18) and an abutment face (21) defining an annular recess (20). The castellations (18) fit into cutouts (22) in the port (3) whereby when said fitting (12) is rotated the castellations have tightening means (38) which force against the castellations (33) of the port (3) forming a seal between sealing faces (24) of the port (3) and abutment face (21) of the fitting (12) to prevent lateral movement and whereby the projection (25) in the port (3) rides up over the ramp surface (19) to lock into the locking recess (27) to prevent rotational movement. The ramp surface being suitably shaped so as to allow for its defamation by manual means to allow for unlocking of the connector. |
