Abstract
A device for connecting male and female piping or tubing, where the female pipe includes an inner wall portion with a first holding section positioned at the inner periphery of the female pipe. The male pipe includes a sleeve with a second holding section positioned on the outer periphery of the male pipe, The device includes a ring-shaped element arranged between the male/female pipes. The ring-shaped element includes at least one axially protruding resilient tongue with a first device engaging the first holding section of the female pipe, and a second device configured to resiliently snap into a holding position within the second holding section of the male pipe when inserting the male pipe into the ring-shaped element and the female pipe.
Claims19
A device, comprising:
- a female part;
- a male part insertable into the female part;
- said female part including an inner wall portion defming at least one first holding section that is an arcuate groove positioned along an inner periphery of said female part,
- said male part including a sleeve with at least one second holding section positioned on an outer periphery of said male part;
- and
- a ring-shaped element, with an axially protruding resilient tongue arranged to be placed between the male and female parts when inserting said male part into said female part through an opening, said resilient tongue including at least one arcuate, radially protruding stop lug extending from an outer periphery of the resilient tongue, the stop lug being configured to extend radially outwardly to insert into said arcuate groove of said female part when inserting said ring-shaped element into said female part, and a protrusion, extending from the resilient tongue and arranged to resiliently snap into a holding position at said second holding section of said male part when inserting said male part into said ring-shaped element and said female parts;
- at least one disengagement element positionable adjacent to the first holding section between the male part and female part, the at least one disengagement element including an outwardly facing radially acting wedge portion,
- the resilient tongue being configured to slide from a first position along an inner circumference of the female part and an outer circumference of the male part to a second position via the application of a turning force, movement of the resilient tongue from the first position to the second position causing a top part of the resilient tongue to contact and slide across the wedge portion to cause the resilient tongue to pivot and separate said female part from said male part,
- the radially acting wedge portion being configured to cause the resilient tongue to return to the first position from the second position automatically if the turning force is no longer applied to the resilient tongue,
- wherein said disengagement element is not integrally formed with the ring-shaped element, the disengagement element being insertable between the male and female parts prior to insertion of said ring-shaped element between the male and female parts during engagement of the male part within the female part.
