A connector for coupling a gases supply means to a conduit, where said conduit includes an electrical wire extending within, throughout or about said conduit, said connector comprising: a male portion of a generally tubular shape, connected in use to one of said gases supply means and said conduit, said male portion having: a main body having two horizontal recesses located on the outer surface of said main body without extending through to the inner surface of said main body, and an electrical connector receiving means (625, 626); a female portion of a generally tubular shape connected in use to the other one of said gases supply means and said conduit, said female portion having: two pivoting flexible members (612, 613) integrally formed with the female portion, the inside edges of each of said pivoting members further including an inwardly extending lip, and an electrical connector means (618, 621); a sliding collar of generally tubular shape, adapted to slide over and about the female portion; wherein in use coupling of said male and female portions by inserting said male portion within said female portion, and sliding said sliding collar over the female portion causes the pivoting members (612, 613) to be pushed inwards and the lips to be pushed into the two horizontal recesses thereby releasably locking the male and female portions (601, 602) together, and wherein said coupling simultaneously causes said electrical connector means (618, 621) to engage with said electrical connector receiving means (625, 626) making a pneumatic seal and electrical connection between said male and female portions (601, 602) and consequently between said gases supply means and said conduit. a male portion of a generally tubular shape, connected in use to one of said gases supply means and said conduit, said male portion having: a main body having two horizontal recesses located on the outer surface of said main body without extending through to the inner surface of said main body, and an electrical connector receiving means (625, 626); a female portion of a generally tubular shape connected in use to the other one of said gases supply means and said conduit, said female portion having: two pivoting flexible members (612, 613) integrally formed with the female portion, the inside edges of each of said pivoting members further including an inwardly extending lip, and an electrical connector means (618, 621); a sliding collar of generally tubular shape, adapted to slide over and about the female portion; wherein in use coupling of said male and female portions by inserting said male portion within said female portion, and sliding said sliding collar over the female portion causes the pivoting members (612, 613) to be pushed inwards and the lips to be pushed into the two horizontal recesses thereby releasably locking the male and female portions (601, 602) together, and wherein said coupling simultaneously causes said electrical connector means (618, 621) to engage with said electrical connector receiving means (625, 626) making a pneumatic seal and electrical connection between said male and female portions (601, 602) and consequently between said gases supply means and said conduit. a main body having two horizontal recesses located on the outer surface of said main body without extending through to the inner surface of said main body, and an electrical connector receiving means (625, 626); a female portion of a generally tubular shape connected in use to the other one of said gases supply means and said conduit, said female portion having: two pivoting flexible members (612, 613) integrally formed with the female portion, the inside edges of each of said pivoting members further including an inwardly extending lip, and an electrical connector means (618, 621); a sliding collar of generally tubular shape, adapted to slide over and about the female portion; wherein in use coupling of said male and female portions by inserting said male portion within said female portion, and sliding said sliding collar over the female portion causes the pivoting members (612, 613) to be pushed inwards and the lips to be pushed into the two horizontal recesses thereby releasably locking the male and female portions (601, 602) together, and wherein said coupling simultaneously causes said electrical connector means (618, 621) to engage with said electrical connector receiving means (625, 626) making a pneumatic seal and electrical connection between said male and female portions (601, 602) and consequently between said gases supply means and said conduit. two pivoting flexible members (612, 613) integrally formed with the female portion, the inside edges of each of said pivoting members further including an inwardly extending lip, and an electrical connector means (618, 621); a sliding collar of generally tubular shape, adapted to slide over and about the female portion; wherein in use coupling of said male and female portions by inserting said male portion within said female portion, and sliding said sliding collar over the female portion causes the pivoting members (612, 613) to be pushed inwards and the lips to be pushed into the two horizontal recesses thereby releasably locking the male and female portions (601, 602) together, and wherein said coupling simultaneously causes said electrical connector means (618, 621) to engage with said electrical connector receiving means (625, 626) making a pneumatic seal and electrical connection between said male and female portions (601, 602) and consequently between said gases supply means and said conduit.
