1. A retainer for securely anchoring a catheter adaptor of the type having an elongated tubular body, a support arm attaching a clip to the adaptor body, and a protuberance disposed on the clip proximal of the support arm, said retainer comprising:

  • a pair of opposing longitudinal walls, each wall defining a series of slots with each slot being sized to receive a portion of the support arm of the catheter adaptor which extends through the slot, and to prevent the support arm from moving in a direction parallel to a longitudinal axis of the retainer; and

    a central channel extending through said retainer about an axis which is generally parallel to said retainer longitudinal axis, said channel being interposed between said opposing longitudinal walls and having a truncated circular cross-sectional shape which extends through an angle greater than 180°

    about said channel axis, such that with the adaptor tubular body positioned within the central channel, said longitudinal walls prevent the adaptor from moving either in transverse or lateral directions which are normal to the longitudinal axis of the retainer.
