Connecting device for fluid conduits and the like

A connection device for use in facilitating a connection of a fluid conduit to a housing means having means defining a recess adapted to receive a connection end of the fluid conduit therein, comprising a unitary annular gripper means encircling the conduit and adapted to be axially slidably received into the recess for effecting a detachable securement of the connection end of the fluid conduit in the recess when the annular gripper means is a first position in the recess, wherein the unitary annular gripper means is provided with an annular actuating part having on an axial end facing an interior of the recess a plurality of circumferentially spaced clamping elements, bending means on the annular gripper means for supporting the clamping elements thereon for movement between a radially inwardly clamping position and a radially outwardly release position and for forcibly yieldably urging the clamping elements radially inwardly so as to engage an outer surface of the connection end when the connection end is inserted into the recess, the clamping elements, when so engaged by the connection end, being urged radially outwardly slightly due to a difference in circumferential dimension between an outer circumference of the connection end and an inner circumference of the clamping elements, a respective clamping element each having a pressing part arranged radially outwardly from the bending means and axially offset to the bending means, each said pressing part being received in a groove-like retaining recess in an inner circumferential surface of the recess of the housing means, the retaining recess having an axially inwardly located side face facing axially outwardly of the recess in the housing means and an axially outwardly located side face spaced axially outwardly of the recess in the housing means therefrom and opposing the inward side face, the pressing parts being located in an intermediate region between the axially inward side face and the axially outward side face, the axially inward side face of the retaining recess defining a support surface having an oblique configuration, the radially outer portion of the support surface being arranged axially closer to the outer end of the recess in the housing means than the radially inner portion of the support surface, the support surface axially opposing the pressing parts in such a manner that when the actuating part is slid axially further into the recess to a second position thereof in a effort to effect a release of the connection end, the pressing parts operatively engage the obliqued support surface and cause the clamping elements to be rocked about the bending means radially outwardly into the release position to allow for the removal of the clamped connection end from the recess in the housing means.
