A clip assembly for securing a rail to a support surface, said assembly comprising:

• a. a base body attachable to said support surface, said base body defining a cavity at an underside said base body, wherein said cavity and said support surface define a space at said underside of said base body, said base body comprising:
• i. a first wall that is adjacent said rail when said base body is secured on said support surface, said first wall also defining an inclined portion;
• ii. a depression configured on said first wall;
• iii. a substantially horizontal slot configured on said base body extending toward said first wall;
• and
• b. a top body assemblable on said base body, said top body comprising:
• i. a rail abutting portion that defines a substantially L-shaped surface to abut said rail;
• ii. a slot configured on said top body;
• c. a screw fittable into said first wall and passes through said slot configured on said top body, wherein a portion of said screw fits into said depression of said first wall to secure said screw while said screw is received within said space, and wherein a shank of said screw abuts a portion of said substantially horizontal slot on said base body and said slot on said top body when a nut is tightened on said shank for securing said top body to said base body to secure said rail,
• wherein said top body and said base body have complementary inclined abutting surfaces, and
• wherein said complementary inclined abutting surfaces, said slot on said top body, and said inclined portion of said base body are inclined at identical angle.
