Claim 15

A connector according to claim 11, wherein said locking tab has a finger protruding into said recess for engagement with the conduit.

Claim 16

A connector according to claim 1, wherein said retaining means comprises a resilient, helical coil tail coupled to said second end and extending away from said body member, said tail being adapted to wrap around the conduit.

Claim 17

A connector according to claim 1, and further comprising sealing means for forming a fluid-tight connection between the conduit and the support.

Claim 18

A connector according to claim 16, wherein said sealing means comprises a sealing member disposed around said resilient legs for sealing between said body member and the support.

Claim 19

A connector for coupling an electrical conduit to a support having an aperture, the combination comprising: a tubular body member having a longitudinal axis and first and second ends and including a plurality of resilient legs with radially extending locking tongues thereon, said legs being located at said first end and being adapted to deflect to pass through the aperture, and retaining means, adjacent said second end, for retaining the conduit therein; and spring means for biasing said body member away from the support when said spring means engages the support, said spring means being rigidly coupled to said body member between said first and second ends whereby said locking tongues and spring means engage opposed sides of the support adjacent the aperture, and wherein said spring means comprises a resilient annular flange coupled to and extending from a hollow sleeve surrounding said body member.

Claim 20

A connector for coupling an electrical conduit to a support having an aperture, the combination comprising: a tubular body member having a longitudinal axis and first and second ends and including a plurality of resilient legs with radially extending locking tongues thereon, said legs being located at said first end and being adapted to deflect to pass through the aperture, and retaining means, adjacent said second end, for retaining the conduit therein; and spring means for biasing said body member away from the support when said spring means engages the support, said spring means being rigidly coupled to said body member between said first and second ends whereby said locking tongues and spring means engage opposed sides of the support adjacent the aperture, and wherein said spring means comprises a resilient annular flange coupled to and extending from a hollow sleeve surrounding said body member.

Claim 21

A connector according to claim 18, wherein said sleeve has a radially inwardly extending annular ring.

Claim 22

A connector according to claim 19, wherein said body member comprises an annular radially extending groove between said first and second ends, said ring engaging said groove in an interlocking fit.

Claim 23

A connector for coupling an electrical conduit to a support having an aperture, the combination comprising: a tubular body member having a longitudinal axis and first and second ends and including a plurality of resilient legs extending outwardly from said first end and being adapted to deflect to pass through the aperture, said legs having locking tongues extending radially outwardly therefrom and retaining means, adjacent said second end, for retaining the conduit therein; spring means for biasing said body member away from the support when said spring means engages the support; and means, located on said spring means and said body member, for rigidly coupling said spring means to said body member between said first and second ends to prevent relative translational movement therebetween, whereby said locking tongues and spring means engage opposed sides of the support adjacent the aperture.

Claim 24

A connector for coupling an electrical conduit to a support having an aperture, the combination comprising: a tubular body member having a longitudinal axis and first and second ends and including a plurality of resilient legs extending outwardly from said first end and being adapted to deflect to pass through the aperture, said legs having locking tongues extending radially outwardly therefrom and retaining means, adjacent said second end, for retaining the conduit therein; spring means for biasing said body member away from the support when said spring means engages the support; and means, located on said spring means and said body member, for rigidly coupling said spring means to said body member between said first and second ends to prevent relative translational movement therebetween, whereby said locking tongues and spring means engage opposed sides of the support adjacent the aperture.
