• a pull handle mounted to rotate from one end of the housing outwardly through the housing open wall and having a blade extension operating through one end of the housing as a pawl;
• wherein the pawl projecting from one end of the housing and connected to the pull latch to move to a closed position when the pull handle is rotated to be within the housing and said pawl to move to an open position when the pull handle is rotated to the fully open position upwardly from the housing;
• a biasing spring positioned to move the pull handle upwardly out of the housing and pawl to the open position;
• and a release button connected to the handle and releasing said handle to move under biasing spring force when said button is operated;
• and
• a flat spring mounting means mounted to the opposite end of the housing from the pawl projection, said flat spring holding the housing to said plate and releasing the housing therefrom, said flat spring being deformable when said housing is inserted or extracted from said mounting opening, said deforming permitting the housing and the flat spring slide there through, where upon the flat spring returns to shape to press against said plate for securing said latch.

• a biasing spring positioned to move the pull handle upwardly out of the housing and pawl to the open position;
• and a release button connected to the handle and releasing said handle to move under biasing spring force when said button is operated;
• and
• a wire-like clamping means for holding the housing to said plate and releasing the housing therefrom, said clamping means being deformable under relatively light pressure to engage and disengage with holding members;
• wherein said plate-type pawl includes a longitudinal aperture which is connected to limit the extent of movement of said pull handle after the disengagement from said button.

• a biasing spring positioned between an inside wall of the housing and a camming portion of the pawl to act to slide the pawl outwardly;
• wherein the pull handle includes a hook portion which cames against the camming portion of the pawl to withdraw it into the housing;
• and
• a wire-like clamping means for holding the housing to said plate and releasing the housing therefrom, said clamping means being deformable under relatively light pressure to engage and disengage with holding members;

A bail clamping structure for holding a housing securely to a plate, said housing extending from an outward face of the plate through a cutout opening in the plate, said clamping structure being quick mount and quick release from the inward face of the plate, said clamping structure comprising:

• a housing having a face flange extending laterally outwardly thereabout and a pivot accommodating structure at one end thereof;
• a bail being sized and shaped to surround a portion of said housing and being pivotally mounted to the pivot accommodating structure of said housing;
• wherein said cutout opening is sized to pass said housing and seat said housing face flange against said outer face of said plate;
• wherein said cutout opening includes bump-out notch openings to pass said bail when said bail is rotated to extend orthogonal to said notch openings;
• and
• receiving structure on opposite sides of the housing for receiving a part of said bail and holding said in fixed engagement with said housing when said bail is rotated to extend parallel to said inside face of said plate;
• and
• wherein said bail is in spring force engagement against said inside face of said plate when said bail is in fixed engagement with said housing and said housing seats through said cutout opening with said flange thereof seated on said outside face of said plate.

A method for securing and quick release mounting of a housing to a plate, said plate having a outside face and an inside face, which housing when mounted extends through a complementary opening in a plate, comprising the steps of:

• providing an opening in said plate for receiving said housing;
• providing an abutment structure on said housing for establishing a fully seated position of said housing in said plate opening;
• providing a resiliently flexible clamp carried on said housing for fixing said housing securely to said plate when said housing is fully seated in said plate opening;
• providing notch-out openings in a portion of said plate opening for passing said clamp;
• rotating said clamping to extend orthogonal to said plate opening;
• providing clamp engagement structure on said housing side walls;
• passing said housing into said plate opening to fully seat it therein by abutting said abutment structure against the outside face of said plate, wherein said orthogonal positioned clamping means passes through said notch-out openings and is entirely on the inside face side of the plate when said housing is fully seated;
• and
• rotating said clamping to extend parallel to the inside face of said plate and engaging said housing side wall clamp engagement structure to fix said clamp thereto, whereby said clamp exerts a spring force against the inside face of said plate holding the housing abutment structure fast against the outside face of the plate.

A wire bail-type quick mount, quick release, clamping device for holding a housing securely on a plate with the housing having an abutment for seating on the outside face of the plate, said housing extending through an opening in said plate to extend beyond the inside face of said plate, whereof the plate opening has a plurality of notch-outs, said clamping device comprising:

• a wire bail mounted onto the side walls of said housing and rotatable from a rotation point on said side wall to extend parallel to the plane of said housing side walls and orthogonal to said housing abutment and also rotatable to extend parallel to the plane of said housing abutment;
• wherein when extending parallel to the plane of said housing abutment said wire bail extends along each side wall of said the housing and around one end of said housing forming an open loop;
• wherein said wire bail portion lengths for extending along each side wall of said housing defines the two side legs of said wire bail, and wherein said wire bail portion length for extending around one end of said housing defines the end section of said wire bail;
• a first resiliently flexible bend in each side leg of said wire bail;
• a wire bail engagement and holding member on each sidewall of said housing, wherein said engagement is achieved by deforming said wire bail side legs to ride over said housing side walls;
• and
• wherein said wire bail rotation point is positioned to pass the wire bail in orthogonal position and said wire bail engagement and holding members through said plate opening notch-outs when said housing is inserted into said plate opening.
