conventional design except for omission of the transverse ridge 32 the supply tubing for intravenous fluid can similarly comprise a connection tubular member 50 adapted to frictionally engage the insert tube 46 and a flexible tubular member 52 which serves to join the connector 50 to a supply conduit 54 leading to a source of intravenous fluid as in the first embodiment the channel 44 will preferably be of sufficient length to receive both the connection between the insert tube 46 and the connecting tubular member 50 and at least a portion of the flexible tubular member 52 as in the first embodiment the body 40 is resiliently compressible transverse to the channel 44 to facilitate transverse compressibility groove means 56 penetrating a lower surface 58 of the channel 44 is provided it is again recommended that this groove means 56 be in the form of a slot or gap preferably extending over half the length of the body 40 the embodiment of fig7 10 also includes means for maintaining transverse compression on side portions 60 and 62 of the body sufficient to hold and secure the tubing connection 48 within the channel a releasable clamp means in the form of a generally c shaped retainer 42 is similarly designed to engage exterior grooves 64 and 66 in the body 40 the retainer 42.
