ABSTRACT:
A hose connector comprises (a) a tubular nipple comprising one end insertable into an end of a hose, the one end defining an annular shallow recess of a depth of 0.2 mm to 0.8 mm, the shallow recess being delimited by a flat bottom and two shoulders defining sharp edges and extending substantially perpendicularly to the cylindrical surface of the tubular nipple whereby a linear pressure is exerted upon a hose whereinto the one tubular nipple end is inserted, (b) a collar concentrically surrounding the one tubular nipple end, (c) a sleeve concentrically surrounding the one tubular nipple end and threadedly connected to the collar, the collar and the sleeve defining an annular groove for receiving the hose end, a portion of the internal collar wall frusto-conically diverging towards the sleeve, and an end of the sleeve facing the frusto-conically diverging internal collar wall portion forming an annular abutment, the conically diverging internal collar wall portion and the annular abutment defining an annular chamber, and (d) at least one toroidal coil spring arranged in the annular chamber opposite the annular shallow recess, the annular abutment having an outer diameter that is slightly larger than a median diameter of the coil spring in a radially tensionless state.
