Abstract
Abstract A swivelable quick connect assembly for use with tubular conduits is disclosed as comprising a housing having an axial bore for receiving one end of the conduit, an elastomeric ring-like seal is disposed in the bore for providing a fluid tight seal between confronting portions of the conduit and the housing, an annular bushing is disposed in the bore for positioning the seal and for guiding the one end of the conduit into nesting relationship with the bore, and a retainer is detachably secured to the housing and is cooperable with an annular projection on the conduit for securing the conduit in its operative position within the bore, the retainer having resilient deformable potions which are adapted to snap over the locking wall upon insertion of the conduit into the housing bore. Also, a safety sleeve is disclosed comprising a body, a tab on the body for indicating whether or not the conduit has been detached from the housing, and a window in the body for indicating whether or not the conduit is properly secured in the housing. Further, a retainer element is disclosed comprising a collar, an orientation means on the collar and at least one or more deflectable bent configuration legs projecting from the collar for retaining the conduit in the retainer element and in the housing.

Claim 1
Independent Claim
275 words
A safety sleeve for enabling a user to visually determine if a conduit has been removed from its connector and, also, to enable the user to visually determine whether or not the conduit is properly inserted into the connector, the conduit formed with at least one annular projection, the connector including a housing formed with an axial bore for receiving the conduit at a first end and for providing a fluid path at a second end, and a retainer element disposed within the axial bore of the housing and having at least one deformable portion for operatively cooperating with the conduit and the housing and preventing withdrawal of the conduit from the housing, said safety sleeve comprising: a body member adapted to be disposed about the conduit and adapted to be inserted into the housing to expand the retainer element to enable the conduit to be removed from the housing; tab means on said body member for indicating whether or not the conduit may have been removed from the connector, said tab means removably secured to and extending above said body member to prevent said body member from being inserted into the housing and when said tab means is removed from said body member to allow the said body member to be inserted into the housing to expand the retainer element to enable the conduit to be removed from the connector and indicate that the conduit may have been removed from the connector; and window means in said body member for enabling visual inspection of the annular projection of the conduit through said window means to determine proper securement of the conduit with the connector.
