Abstract: There is provided a connecting clasp for joining adjacing modular units of a solar collector mounted on roofs or other surfaces, including two substantially upright walls defining between them a space of a width capable of accommodating the end portions of spacer bars of the solar collector and a plurality of catches with inwards and downwards inclined top faces projecting from inside faces of the two upright walls. By application of force to a spacer bar seatable on the upper edges of the top faces of the catches, the upright walls are spread apart, letting the spacer bars enter the space until the catches snap into recesses provided in the spacer bars, thereby locking the clasp into position.

Abstract: There is provided a clamp for securely attaching a component of a solar collector to a surface, including an upper clamp member and a lower clamp member. The lower member is fixedly mountable to the surfaces and the upper and lower clamp member are connectable to one another by locking members, defining between themselves an aperture for the accommodation of the component. The aperture has a length dimension and a height dimension, wherein the length dimension substantially exceeds the height dimension.
