Retention device
First Claim
1. A retention device for retaining objects, comprising a retainer body having a passage extending therethrough and having an elongated strap with one end portion joined at a junction to said body and an opposite free end portion insertable into and through said passage to form said strap into an object-retaining loop;
- said strap having a longitudinal series of transversely-extending ratchet teeth along one surface thereof;
said body including a bottom platform;
a first substantially flexible side wall pivotally connected to said platform, extending along said passage, and having an upper portion;
a second substantially rigid side wall connected to said platform, extending along said passage and having an intermediate portion and an upper portion;
a flexible top wall joined to said upper portion of said first side wall and being connected by a flexible web to said intermediate portion of said second side wall; and
latching means extending downwardly from a central portion of said top wall for engaging said teeth and preventing reverse movement of said strap in said passage;
said latching means being shifted out of engagement with said teeth when said first side wall is squeezed towards said second side wall to cause pivotal movement of said first side wall and lateral flexure of said central portion of said top wall.

Abstract
A retention device, particularly useful for drainage tubes and the like, having a pad for adhesive attachment to a patient'"'"'s skin at the exit/entry site for a post-surgical drainage tube. The device includes a retainer body secured to the pad and provided with a strap to be looped and tightened about the drainage tube for immobilizing that tube. A passage in the body receives the free end of the strap and a latching mechanism prevents retraction of the strap unless the sides of the body are squeezed towards each other to alter the configuration of the body'"'"'s side and top walls and cause lateral disengagement of a restraining pawl from the ratchet teeth of the strap.
