Abstract: A lamp (L) having tubular end contacts (L1) adapted for insertion into opposite lamp holders (P), each lamp holder (P) having a body (S) in an insulating material and a contact element (C) shaped to provide a seat for the lamp contact (L1). In one embodiment, the seat comprises a cylindrical central portion (C1) positioned between flexible opposite arched walls (C2) with two upper divergent flanges (C2a). The lamp end contacts (L1) are positioned between the flexible arched walls (C2) of the contacts (C), in order to receive the cylindrical parts (C1) of the seats of the contact elements (C) inside the end contacts (L1) of the lamp (L). By the rotation of the lamp (L) around the cylindrical parts (C1) of the contact elements (C), an unwanted removal of the lamp (L) from the lamp holders (P) is prevented.

Abstract: The lamp holder for linear lamps, with body in insulating material and a contact element, includes an element shaped in a way to have a seat, for the contact of the lamp. The seat has a cylindrical central portion around which there are two opposite arched walls flexible-enlargeable with two upper divergent flanges. The lamp has end contacts between the flanges of the contacts of the lamp holder in order to receive the cylindrical parts of the seats of the contact elements inside the end contacts of the lamp. By the rotation of the lamp around the cylindrical parts of the contact elements in the lamp holder the direct removing of the lamp from the lamp holder is avoided.
