ABSTRACT:
A device is disclosed for connecting two rigid tubular objects. The device includes a male part and a female part. The female part includes a sleeve which, at one of its ends, is provided with a recess. The male part includes a tube portion which, at one of its ends, is provided with a transverse edge formed by an indentation arranged in the outer wall of the male part. A sleeve-shaped element is arranged to be placed between the parts when inserting the male part into the female part. The element is provided with a resilient tongue with a first device/element which, during insertion of the element into the female part, resiliently engages the recess thereof and a second device/element, which during insertion of the male part into the element, resiliently snaps into place behind the transverse edge of the male part. The resilient tongue allows separation of the female part and the male part by turning of the element relative to the male part to a position where the second device/element of the resilient tongue is arranged radially outside the transverse edge of the male part. The resilient tongue is, in turning for separation, with a portion in the recess of the female part raised radially outside the transverse edge of the male part.
